What is sinusoidal sequence?

A sinusoidal sequence is the fundamental periodic signal having just one single frequency.

What is the meaning of sinusoidal fidelity?

An important characteristic of linear systems is how they behave with sinusoids, a property we will call sinusoidal fidelity: If the input to a linear system is a sinusoidal wave, the output will also be a sinusoidal wave, and at exactly the same frequency as the input.

Is sinusoidal Signal linear?

Sinusoidal stimuli have a special relationship to shift-invariant linear systems. A sinusoid is a regular, repeating curve, that oscillates around a mean level. The sinusoid has a zero-value at time zero.
