Unformatted text preview: (See T2.23 and T2.25.) Q5) Suppose the two waveforms in Q4 are passed through a filter with transfer function shown below. For each of the two waveforms, draw the magnitude spectrum and energy spectra at the filter’s output. (See T2.26.) Q6) (1) Derive the Fourier transform of 1; (2) Derive the Fourier transforms of sin(2 π f t ) and cos(2 π f t ); (3) Let X ( f ) be the Fourier transform of x ( t ). Determine the Fourier transforms of x ( t )sin(2 π f t ) and x ( t )cos(2 π f t ). 500 0 500 Hz H ( f ) 1 0 1 2 msec msec (b) 1 volts 2 volts 3 volts 1 0 1 msec msec (a)...
