WebApr 24, 2012 · But you need at least two samples per cycle (2*pi) to depict your sine wave. Otherwise you'll get an alias frequency, and in you special case the alias frequency is infinity as you produce a whole multiple of 2*pi as step size, thus your plot never gets its arse off (roundabout) zero. Using Rick's code you'll be granted enough samples per period. WebFor a sine wave modulation, the modulation index is seen to be the ratio of the peak frequency deviation of the carrier wave to the frequency of the modulating sine wave. If , the modulation is called narrowband FM (NFM), and its bandwidth is approximately . Sometimes modulation index is considered as NFM, otherwise wideband FM (WFM or FM).

WebFeb 12, 2024 · In general, a pure steady real sinusoidal signal can be modeled as: x ( t) = A cos ( θ t + ϕ) The argument θ t + ϕ is usually called the "phase" of the signal which can be confusing as the same term is also used for the ϕ, so let's call it the phase function.
