OFDM is a technique used in modern broadband wireless communications systems. To mitigate the effect of dispersive channel distortion in high data rate OFDM systems, CP is introduced to eliminate ...

Signal modulation is one of the most basic and important concepts in the RF industry. It consists of using the variation of one or more parameters of a carrier signal to transmit information, ...

We’ve done quite a bit with Google Sheets and signal processing: we’ve generated signals, created filters, and computed quadrature signals. We can pull all that together into an educational model for ...

Software-defined radio (SDR) is a very powerful concept. Its technologies provide software implementation of modulation, interference management, and capacity enhancement techniques over a broad ...

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, ...

Part of the reason for the confusion between chorus, phasing and flanging is the close similarity in sound between the three. Arguably the technical differences between them are subtle, but when ...

Electronic communications began as digital technology with Samuel Morse’s invention of the telegraph in 1845. The dots and dashes of his famous code were the binary ones and zeroes of the current ...

First I’ll tell what you already know. Back in the day, AM broadcasting was king and FM was commercial-free. Things changed in the 1970s as FM grew in popularity. Here we are 40+ years later with many ...
