Unformatted text preview: 6.  Consider the CT signal x ( t ) = rect( t A ), where t is in units of seconds and A = 7. (a) Analytically determine the FT of this signal and plot in Matlab. (b) Sample x ( t ) with a sampling period T = 1. Determine, analytically or numerically, the DTFT of the sampled signal and plot in Matlab. (c) Compare the continuous and DT FTs over the frequency range - to . (d) Take the result of part (a) and create the spectrum Y (e j ) = X (e j )+ X [e j ( +2 ) ]+ X [e j ( -2 ) ]. Plot this spectrum from - to and compare with parts (a) and (b). 1...
