The function which relates output of a system to the input(signal) of a system isDeselect Answer Periodic function Non-periodic function Transfer function None of the above 2. A discrete signal is said to be odd or asymmetric if x(-n) is equal toDeselect Answer X(n) 0 –x(-n) ∞ 3. Nyquist bit rate formula defines the theoretical maximum bit rate for which channelDeselect Answer Noisy Noiseless bandpass lowpass 4. The equation y(t) = a x(t)+b comes under which systemDeselect Answer Linear for any value of b Linear if b > 0 Linear if b < 0 Non-linear 5. What form of waveform is shown here?Deselect Answer A Binary Signal A Multi valued digital signal An Analogue signal Noise Signal 6. A continuous-time periodic signal x(t), having a period T, is convolved with itself. Then the resulting signal isDeselect Answer Not Periodic Periodic having a period 2T Periodic having a period T Periodic having a period T/2 7. The Inverse Fourier Transform of u(ω) isDeselect Answer (1/2) δ(t) + 1/πt ( ½) δ(t) 2 δ(t) + 1/πt δ(t) +sgn(t) 8.
