WebMar 21, 2024 · From references I saw that a linear sweep/chirp function creates frequencies which are not the actual frequencies which you can count if you see the output. There are formulas for calculating the right frequency for the input, but I don't understand why this is the case, as for a constant frequency this does work.

WebJan 22, 2009 · A swept-frequency or chirp signal has a time-varying frequency. In the simplest and most common case, the frequency varies linearly in time between a starting value and an ending value over a defined duration. Such a signal can be expressed as: x (t) = A cos ( 2 pi ( (f2 - f1) t**2 / (2 d) + f1 t + P) )
