Abstract: Based on the principle of 2FSK modulation and demodulation, Simulink models for 2FSK modulation and demodulation were established with the Simulink software tools, and simulation analysis ...

[brmarcum] takes us back to analog building block basics with his Frequency Modulation and Demodulation tutorial. Frequency Modulation (FM) sounds simple at first, but understanding the electronics ...

How does the process of communication happen? The signal should travel between the transmitter and receiver. In order for the signal to be transmitted, it should have a transmittable form. To do so it ...

Compared to the simple diode needed to demodulate AM radio signals, the detector circuits used for FM are slightly more complicated. Wrapping your head around phase detectors, ratio detectors, ...

Abstract: Gearbox fault diagnosis is important for ensuring the safety and running quality of many sorts of machinery. When fault exists, gearbox vibration signals feature amplitude modulation as well ...
