- Generate FM noise sidebands on a carrier using randn fn
- License: Freeware
- Price: 0.00

The file calculates and plots FM noise sidebands for a carrier. It also does sinusoidal modulation. This simple way of adding noise to a carrier is useful for simulation of PLLs. It turns out, though, that the mean of the randn function is not as close to zero as it could be, and this causes the fft to generate extra sideband energy, which makes it appear as if the noise is not what would be expected.

function y = getiq(x,freq) this takes in the frequencies X that were received at a rate of FREQ and gives you a complex value which is I and Q - this is used when you have frequency X changing and the phase is cumulative - meaning it does not start each new frequency at the same spot OR function y = getiq(data,freq,fc) this takes in frequencies X that were received at a rate of FREQ and gives you a complex value which is I and Q based around a center frequency FC this is used when you have frequency X changing and the phase is cumulative - meaning it does not start each new frequency at the same spot.
