In amplitude modulation, current power is adjusted to control instantaneous magnetron output.
If the amplitude term VP is varied, the resulting modulation is called as Amplitude Modulation (AM), if f term is varied, the resulting modulation is called as Frequency Modulation (FM), and if F is varied, the resulting modulation is called as Phase Modulation (PM).
The amplitude modulation and the phase modulation are sampled by different classes of electroreceptors and processed in parallel by the hindbrain (Rose et al.
