Whether this envelope approximation technique yields sufficiently accurate results is for the user to decide. Its accuracy may be below the requirements of most AM (amplitude modulation) detection ...

The diode detector provides the amplitude or envelope of the signal (s) within that wavelength. A high impedance or highly sensitive ear piece converts this envelope to an audible signal that you ...

There are many different varieties of modulation but they all fall into three basic categories, namely amplitude modulation, frequency modulation and phase modulation, although frequency and phase ...

*3 Amplitude modulation (AM) A pattern of slow changes in the amplitude of a signal (amplitude envelope). Important parameters describing amplitude modulation are its speed and depth (Figure 2).

Envelope follower When we set an envelope to control a sound’s amplitude over time, we’re defining the dynamic response of the signal. However, what happens if we take the volume level of a sound and ...
