This document describes an experiment on low-pass and high-pass filters. It includes the theoretical background of different filter types and how to analyze them using Bode plots. The experiment uses resistor-capacitor filters to study low-pass and high-pass behavior. For the low-pass filter, the cutoff frequency is measured from the Bode plot and matches the calculated value based on the component values. Changing the resistor changes the cutoff frequency as expected, while maintaining the same roll-off rate.

DSP_2018_FOEHU - Lec 06 - FIR Filter DesignAmr E. Mohamed

This lecture discusses the design of finite impulse response (FIR) filters. It introduces the window method for FIR filter design, which involves truncating the ideal impulse response with a window function to obtain a causal FIR filter. Common window functions are presented such as rectangular, triangular, Hanning, Hamming, and Blackman windows. These windows trade off main lobe width and side lobe levels. The document provides an example design of a low-pass FIR filter using the Hamming window to meet given passband and stopband specifications.

Experiment 3 Low Pass Filter Katrina Little

The document summarizes an experiment that tested and characterized first-order and fourth-order low pass filters. Key findings include: - The cutoff frequency was measured to be 1.1 kHz for the first-order filter and 10.2 kHz for the fourth-order filter, close to theoretical calculations. - The first-order filter had a rolloff rate of 13.08 dB/decade while the fourth-order was 49.6 dB/decade as expected for higher order filters. - Both filters were able to suppress harmonics and convert a square wave input to a sine wave output as intended applications of low pass filters.

This document describes an experiment to analyze the frequency response characteristics of passive first-order low-pass and high-pass filters. The objectives are to plot the gain and phase responses of RC filters, determine cutoff frequencies, and observe how component values affect cutoff. Procedures are provided to simulate low-pass and high-pass RC filters, measure their gain and phase curves, and calculate cutoff frequencies. The results show that the simulated and calculated cutoff frequencies match closely, and that changing resistor or capacitor values only affects cutoff frequency as expected, without changing the -20dB/decade roll-off behavior of a single-pole filter.

Exp passive filter (4)Sarah Krystelle

This document describes an experiment to analyze the frequency response of passive low-pass and high-pass filters. The objectives are to plot the gain, phase, and cutoff frequency of first-order RC filters and determine how component values affect cutoff frequency. For the low-pass filter, the cutoff frequency decreases as resistance or capacitance increases. For the high-pass filter, cutoff frequency also decreases with increasing resistance or capacitance. Both filters exhibit a roll-off of approximately 20 dB per decade of frequency change above or below the cutoff frequency, as expected for a single-pole filter.

Data converter modeling�βο��Y��1Tsuyoshi Horigome

This chapter discusses modeling ideal data converters like ADCs and DACs using SPICE behavioral elements. This allows analyzing mixed-signal circuit performance through SPICE simulation more efficiently. Behavioral models are generated for ideal ADCs and DACs. Sampling a signal replicates its spectrum at intervals of the sampling frequency, which can cause aliasing. SPICE is used to analyze signals in the frequency domain to study the effects of conversion. Ideal anti-aliasing and reconstruction filters are discussed, which should have linear phase and a cutoff frequency of half the sampling rate.

This document describes an experiment on passive low-pass and high-pass filters. The objectives are to analyze the gain-frequency and phase-frequency responses of first-order R-C filters, determine cutoff frequencies, and observe how component values affect cutoff frequencies. The experiment involves using a function generator and oscilloscope to obtain Bode plots of R-C filter circuits. For a low-pass filter, the gain drops by about 20dB per decade above the cutoff frequency as expected. For both low-pass and high-pass filters, the cutoff frequencies calculated from component values match closely with measured values from Bode plots.

1) A superheterodyne receiver converts incoming radio frequencies to a fixed intermediate frequency (IF) through frequency mixing in order to improve selectivity. It does this by mixing the incoming signal with a local oscillator signal, producing the IF signal and other sum and difference frequencies. 2) The local oscillator frequency is chosen such that the difference between it and the incoming signal frequency equals the IF. All filtering then occurs at this single IF, improving selectivity over a tunable radio frequency filter. 3) A potential issue is that the mixing process can also produce the "image frequency," which is equal to the local oscillator plus or minus twice the IF. A preselector filter before the mixer is used to filter out image frequencies

Exp passive filter (7)Sarah Krystelle

This document describes an experiment to analyze the frequency response of passive low-pass and high-pass filters. The objectives are to plot the gain and phase responses of first-order RC filters, determine cutoff frequencies, and observe how component values affect cutoff frequency. Simulation results show that low-pass filters pass low frequencies and attenuate high frequencies above the cutoff frequency. High-pass filters do the opposite, passing high frequencies and attenuating low frequencies below the cutoff. For both filters, the cutoff frequency is determined by the RC time constant, and increasing or decreasing resistance and capacitance values lowers the cutoff frequency as expected. The phase response also shifts as expected, with about a 45 degree phase shift at the cutoff frequency for both single

It describes: - Integer boundary spurs that occur at integer multiples of the Phase Frequency Detector (PFD) frequency and are stronger near integer boundaries. - How varying the PFD comparison frequency by changing the reference frequency or reference divider can change where integer boundary spurs occur, allowing frequencies furthest from the desired signal to be avoided. - ADIsimFrequencyPlanner, a tool that simulates spur powers over an output frequency range and selects the optimum PFD frequency at each step to minimize spurs.

Requirements Engineering for Secure SoftwareDr Sarika Jadhav

Security requirements are often treated as generic lists of features, neglecting system-specific needs and the attacker's perspective. A systematic approach to security requirements engineering is crucial to avoid this problem. Requirements engineering defects can cost 10 to 200 times more to correct once the system is operational. Software development takes place in a dynamic environment, causing requirements to constantly change.

In this talk, I dove deep into the world of agents, starting with some history of the term. We explored the core properties of agents, like autonomy, social ability, reactiveness, and proactiveness, and how these translate into the agentic systems we're seeing today. I broke down the anatomy of a foundation model-based agent, discussing environments, memory types (procedural, semantic, and episodic), and the role of external tools . We also looked at how these agents reason and plan, and even briefly touched on the concept of "theory of mind". Finally, I walked through some examples from research papers, like generative agents and software developer agents. I wrapped up with a look at the open research challenges, including control, human-agent interfaces, and evaluation. Video recording of the talk: https://www.youtube.com/watch?v=fuag-KiPijQ
