WebExplanation: Frequency is the number of occurrences of a repeating event per unit of time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency. WebDec 9, 2024 · Therefore, the Fourier transform of cosine wave function is, F[cosω0t] = π[δ(ω − ω0) + δ(ω + ω0)] Or, it can also be represented as, cosω0t FT ↔ π[δ(ω − ω0) + δ(ω + ω0)] The graphical representation of the cosine wave signal with its magnitude and phase spectra is shown in Figure-2.

WebAnswer: It is. In general, a function f(t) defined on \mathbb{R} is periodic if we can find a value T such that f(t) = f(t + nT) for every t \in \mathbb{R} and n \in \mathbb{Z}. In this case we call T the period of the function or signal. We often choose the value T to be positive.
