Question

Use the following Matlab script to compute the coefficients for an FIR digital filter. order $=40$ wc $=0.491$ type $=$ high'; b1 = fir1(order, wc, type); order $=40$; $w c=0.491 ;$ type $=$ "high"; $b 1=$ fir1(order, wc, type); Use the Matlab function freqz to plot the magnitude and phase plots for the filter designed using this script which we will call $H(z)$ for this problem.

   Use the following Matlab script to compute the coefficients for an FIR digital filter.
order $=40$
wc $=0.491$
type $=$ high';
b1 = fir1(order, wc, type);
order $=40$;
$w c=0.491 ;$
type $=$ "high";
$b 1=$ fir1(order, wc, type);

Use the Matlab function freqz to plot the magnitude and phase plots for the filter designed using this script which we will call $H(z)$ for this problem.

Instant Answer

Step 1

First, we need to define the order, cutoff frequency, and type of the filter. In this case, the order is 40, the cutoff frequency is 0.491, and the type is "high". Show more…
