Q6: Signal Spectra Manipulation of Signals

Time shifting of a signal preserves its amplitude spectrum.

• True

• False

Time reversal of a signal does not change its phase spectrum.

• True

• False

Time shifting of a signal can be represented mathematically by multiplying the signal in the time domain by a complex exponential function.

• True

• False

Time reversal of a signal does not change its energy.

• True

• False

Time shifting a discrete time signal does not affect its frequency content.

• True

• False

Time reversal of a periodic discrete time signal results in another periodic signal with the same period.

• True

• False

Shifting a discrete time signal to the right by 𝑛n samples is equivalent to shifting it to the left by −𝑛−n samples.

• True

• False

Time reversal and time shifting are linear operations that can be combined in any order.

• True

• False

Time shifting of a discrete time signal involves adding a constant delay to each sample of the signal.

• True

• False

Time reversal of a discrete time signal involves reversing the order of its samples.

• True

• False
