Escuti/Masnari 2007 ECE200 – Fall 2007 – Homework 9 Filters and Operational-Amplifiers Page 1 of 5 Problem 1 – [10 pts] The frequency response of a band- pass filter and the power spectrum of the input signal are shown below. Find and sketch the power spectrum of the output signal. Problem 2 – [16 pts] The transfer function (frequency response) of a certain band-pass filter is given by (a) Calculate the voltage gain Av(f) from 0 to 6000 Hz in steps of 1000 Hz (i.e. a total of seven frequencies). (b) Find the 3-dB cut-off frequency of the filter using either G(f) or Av(f). (c) The following signal is passed through this filter (which has units of Volts). Find the output signal. (d) Find the total signal power at the filter output.
