Assignment Assignment 1 , figure shows Fourier spectra of signalsg1(t) andg2(t). Determine the Nyquistinterval and the sampling rate for signalsg1(t),g2(t),g21(t),g32(t), andg1(t)g2(t). , the Nyquist sampling rate and the Nyquist sampling interval for the signals:(a)sinc(100 t);(b)sinc2(100 t);(c)sinc(100 t) + sinc(50 t);(d)sinc(100 t) + 3sinc2(60 t);(e)sinc(50 t) sinc(100 t).
) times the convolution of their spectra. From width property of the convolution, the width of the convoluted signals is the sum of the widths of the signals convolved. Therefore, the BW of the product is 25+50=75 Hz. The Nyquist rate is 150 Hz. 3. Lathi 6.1-4: The BW of the signal g(t) is 5 Hz (10… rad/s), since the FT as below: g(t) = sinc2 ...
