Supplemental

• Part 1: CT and DT Rectangular Pulses
• Part 2:
  • Output for an three-point averaging filter and first-order difference filter
  • Notes for In-Lecture Assignment #4 on Deconvolution from fall 2024 and fall 2023

• Part 1: When to use CT Analog vs. DT Digital Filters
• Part 2:
  • FIR Filter with Gaussian Shape
  • Homework 4.2 FIR Filter
  • In-Lecture 4 assignment on Deconvolution notes

• FIR averaging filter: coefficients and passes low frequencies and attenuates high frequencies
• FIR filter output signal is convolution of the input signal and filter coefficients
• Coefficients for an FIR filter are the filter's impulse response
• FIR filtering and impulse responses
