Question

If a signal does not change at all, its frequency is zero. If a signal changes

instantaneously, its frequency is infinite. Three components of a sine wave

are amplitude, frequency and phase of a signal. The change in a signal shows

the relation between signal’s amplitude w.r.t to time whereas the phase is

not shown. Explain your answer why we cannot explicitly show phase in a

time-phase plot?
please give me answer quickly

Answer 1

If a signal does not change at all, its frequency is zero. If a signal changes instantaneously, its g g y frequency is infinite. Phase describes the position of the waveform relative to time 0. A sine wave is offset 1/6 cycle with respect to time 0 A sine wave is offset 1/6 cycle with respect to time 0.
