**Frequency Response of Filter**

**AIM**

**:-**To find frequency response of filter for specified coefficients.

**THEORY: -**Filter with coefficients are given. The frequency – magnitude plot gives the frequency response.

**PROGRAM: -**

b = [ 0.0995 0.1989 0.0995 ];

a = [ 1 -0.9316 0.3294 ];

[ h w ] = freqz ( b, a, 100 );

y = abs(h);

i = freqz( b, a, 100, 200 )

plot(i)

semilogx(w, y)

**RESULT: -**Frequency response of specified filter is plotted.
