Introduction

The project involves the design of a digital bandpass filter with the following specifications:

Passband Center Frequency f0 = 2000 Hz

Sampling Rate fS = 8000 Hz (8000 samples/second)

3 dB Bandwidth (1/2 power region) B = 500 Hz

Filter is to consist of 2 poles and 2 zeros

Unity gain (no amplification or attenuation) at the peak frequency

Once designed, the filter characteristics were tested using a number of methods. The steps involved in the design of the filter and results of these tests are included in this report.
