How does Matlab calculate bandwidth of a signal?
Description. bw = powerbw( x ) returns the 3-dB (half-power) bandwidth, bw , of the input signal, x . bw = powerbw( x , fs ) returns the 3-dB bandwidth in terms of the sample rate, fs . bw = powerbw( pxx , f ) returns the 3-dB bandwidth of the power spectral density (PSD) estimate, pxx .
How do you change the frequency range in Matlab?
w = linspace(0,pi); h = freqz(b,a,w); calculates the complex frequency response at the frequency points in w for the filter defined by vectors b and a . The frequency points can range from 0 to 2π.
How do you plot a frequency plot in Matlab?
plot(f,abs(X)/N); xlabel('Frequency (in hertz)'); title('Magnitude Response');
