A second-order Butterworth filter, has 3-dB bandwidth of 500 Hz. Determine the unit impulse response of the filter, and use it to compute the noise-equivalent bandwidth of the filter. Check your result against the appropriate special case of Example 6.9.
Example 6.9
What is the maximum message bandwith for which the system operates satisfactorily? Determine the output signal to quantizing noise ratio when a full-load sinusoidal modulating wave of frequency 1 MHz is applied to the input.
(d) Use the colon operator to create a matrix D by extracting the first through third columns of matrix A. (e) Create a matrix F by extracting the values in columns 2, 3, and 4 and combining them into a single column matrix. (f) Create a matrix G tha..
Consider the difference equation: y(n)=(5/6)y(n-1) - (1/6)y(n-2) + x(n) where x(n) = 2^n u(n) and y(n) = 0 for all n
