The function which relates output of a system to the input(signal) of a system isDeselect AnswerPeriodic functionNon-periodic functionTransfer functionNone of the above 2. A discrete signal is said to be odd or asymmetric if x(-n) is equal toDeselect AnswerX(n)0–x(-n)∞ 3. Nyquist bit rate formula defines the theoretical maximum bit rate for which channelDeselect AnswerNoisyNoiselessbandpasslowpass 4. The equation y(t) = a x(t)+b comes under which systemDeselect AnswerLinear for any value of bLinear if b > 0Linear if b < 0Non-linear 5. What form of waveform is shown here?Deselect AnswerA Binary SignalA Multi valued digital signalAn Analogue signalNoise Signal 6. A continuous-time periodic signal x(t), having a period T, is convolved with itself. Then the resulting signal isDeselect AnswerNot PeriodicPeriodic having a period 2TPeriodic having a period TPeriodic having a period T/2 7.
