How do you calculate power of a signal in Matlab?
Matlab's Norm function:
To compute the total power of the signal x[n] (as in equation (1) above), all we have to do is – compute norm(x), square it and divide by the length of the signal.
How do you find the power and energy of a signal in Matlab?
energy=limit(y(N),N,inf); z(N)=y(N)/(2*N+1); pow=limit(z(N),N,inf);
How do you find the power of a sine wave in Matlab?
Theoretical Power of a Single Sinusoid
As a first example, estimate the average power of a sinusoidal signal with a peak amplitude of 1 and a frequency component at 128 Hz. Fs = 1024; t = 0:1/Fs:1-(1/Fs); A = 1; F1 = 128; x = A*sin(2*pi*t*F1); Plot a portion of the signal in the time domain.
How do you find the power spectrum of a signal in Matlab?
p = pspectrum( x , fs ) returns the power spectrum of a vector or matrix signal sampled at a rate fs . p = pspectrum( x , t ) returns the power spectrum of a vector or matrix signal sampled at the time instants specified in t .
