My Response To Frequency. Now that you know the importance (and limitations) of amplitude variations in frequency response graphs, you might ask: “does the frequency range tell us anything at all?” ...

Figure 3-11. Spectra of frequency-modulated signals with various values of modulation index for a constant modulation frequency. It can be seen that for small values of the modulation index M (e.g. M ...

Oscillation frequency is affected by waveshape and amplitude changes, but waveshape and amplitude are independent of frequency and each other. Therefore the easiest setting method is to adjust ...
