Description
Description
The purpose of this assignment is to design, code, and test a C program that serves as a
FIR filter for discrete data. The math for an FIR filter is:
1
0
( ) ( ) ( )
M
k
y n h k x n k for all n
−
=
= −
Requirements
The following are the requirements of the filter:
• The filter shall accept 7 floating point filter coefficients.
• The filter shall accept 512 floating point input data samples
• The filter shall produce 512 output data samples which are the filtered values.
• The calculation of the first 6 outputs result in negative input data index and shall
by handled by utilizing the first sample
• The filter coefficients can be found with the Matlab command >h=fir1(6,0.1).
• The input data can be generated with Matlab command >x=0.1*randn(1,512).
• The desired output data can be generated with Matlab command >y=filter(h,1,x).
• The filter shall be testing for constant input data with no shift in output data
expected
• The filter shall be tested with single value of 1 at location 256 in the input data
and the filter coefficients are expected as output data values
• The filter shall be tested with noisy input data with noise reduced output data
expected
Assignment Submission Requirements
The following are the submission requirements for the assignment:
• The files will be submitted to Canvas
• The C code with compile instructions in the banner
• The test code with compile instructions in the banner
• A screen shot of your filter coefficients test of your code showing the correct filter
coefficients produced.
