Modulation is fundamental to electronic communications. The modulating signal might be analog in nature (voice or music) or digital bit streams. Most modern communication systems are digital, using ...

Optical communication systems have evolved significantly over recent years with the advent of advanced modulation techniques designed to enhance spectral efficiency and mitigate interference. Offset ...

Two things have been overlooked with phasing amplitude modulation. One is the importance of pulse modulation; the other is that logic gates can be used for analog signal processing. Both of these ...

Quadrature Amplitude Modulation (QAM) has been a fundamental component in the evolution of mobile connectivity. As the demand for faster data speeds and more efficient network utilization continues to ...

Varying the voltage of a carrier or a direct current in order to transmit analog or digital data. Amplitude modulation (AM) is the oldest method of transmitting human voice electronically. In an ...

New modulation schemes don’t come along very often. In fact, it has been years…decades really…. since any new modulation method has been invented. Remember there are only three basic ways a carrier ...

The modulation scheme 16FSK is pretty unusual and not widely used. Yet it is now available in a new IC from CML Microcircuits. And it offers some unusually good benefits for those of you building low ...
