WebModulation is like hiding a code inside the carrier wave. Recall that any wave has three basic properties: 1) Amplitude – the height of the wave 2) Frequency – a number of waves passing through in a given second 3) Phase – where the phase is at any given moment. There are different strategies for modulating the carrier wave. WebPlanetary gearbox vibration signals have strong modulation features due to the amplitude modulation and frequency modulation (AM-FM) effect of gear faults, as well as the amplitude modulation (AM) effect of time-varying vibration transfer paths, on gear meshing vibrations. This results in an involute sidebands structure in Fourier spectrum, possibly …

WebJun 9, 2024 · One of the last stages I referred to as an “Envelope Detector.”. This stage is a very simple circuit consisting of one diode, one capacitor, and one resistor. These 3 amigos convert a “multi-frequency” input signal, called a modulated signal, into a single-frequency output signal. Here is an example schematic for an envelope detector:

WebIn this system, a voltage controlled oscillator (VCO) is phase locked by a feedback loop, which forces the VCO to follow the frequency variations of the incoming FM signal. The low-frequency error voltage that forces the VCO's frequency to track the frequency of the modulated FM signal is the demodulated audio output.
