Question

Consider the square wave shown in Fig XXXXXXXXXXFind the power spectral density, average power, and autocorrelation function of this square wave. Does the wave have dc power? Explain your answer.

Robert · Accepted Answer

From the given waveform, 
 ( )            
 ( )             
Consider an equation for power spectral density, 
  ( )  ∑ | ( )|
  (     )
 
    
 
 ∑ ( )   (     )
 
    
 
 ∑  (     )
 
    

The power spectral density gives the power distribution and is non negative, real and even.
