Testing Filters in Rice DSP Lab

Module by: Hyeokho Choi. E-mail the author

Summary: This module explains how to test the implemented discrete-time filters in Rice DSP laboratory.

Testing filters in Rice DSP Laboratory

You can test the implemented filters using the tone generator and spectrum analyzer on the PC.

  1. Connect the soundcard tone generator to the codec microphone jack to input 5kHz sine wave. Connect the oscilloscope to observe both the codec input and output. As you change the frequency of the sine wave, observe how the amplitude of the filter output changes.
  2. Input white noise from PC sound card to the codec input and observe the spectrum of the filter output using the spectrum analyzer program. Can you see the filter frequency response?
