A 50-MHz FM signal is desired to have a frequency deviation of 24 kHz. The output of early stages of the transmitter is a 5-MHz signal with a frequency deviation of 4 kHz. How can the desired output ...

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, ...

Modulation is the act of translating some low-frequency or baseband signal (voice, music, and data) to a higher frequency. Why do we modulate signals? There are at least two reasons: to allow the ...

Frequency Modulation Boxes in ARC Raiders are slowly becoming one of the most wanted items, and here's how you can farm them ...

The average textbook definition of modulation reads: modulation is a process in which the frequency, phase or amplitude of a carrier wave varies in step with the instantaneous value of the modulating ...

Have you ever heard terms like modulation scheme, orthoganal frequency division multiplexing (OFDM), or symbol rate and scratched your head? As new wireless standards emerge, we get excited about the ...

The key parameters of the FSS technique and their impact on EMI performance. How to evaluate FSS performance using simulation, ICs, and a signal generator. Frequency spread spectrum (FSS) is a ...

There are two radio modulation schemes everyone should know. Amplitude modulation changes the amplitude — or ‘volume’, if you will — of a carrier frequency and turns all radio into channels owned and ...
