In Part 3 of RF Fundamentals, we will focus on the challenges related to the need to generate and demodulate analog and digitally modulated signals in the RF signal chain. We’ll review CW signal ...

In RADAR, signals are transmitted as pulse frequency modulated signals. RADAR uses Frequency Modulated Continuous Wave (FMCW), a continuous varying frequency signal modulated at a known rate over a ...

fixed-width square wave pulse at a set point in the received FM signal’s waveform, usually at the zero-crossing point. Since the frequency of the modulated carrier changes, the duty cycle of the ...

QAM Modulator and Demodulator combine two amplitude modulation signals into a single data transfer channel: 1. Technique of modifying any one characteristic (amplitude, frequency, or phase) of a ...

Software-Defined Radio and the Magic of Frequency Modulation The world around us hums with invisible signals, carrying everything from our ...

A new technical paper titled “Reconfigurable signal modulation in a ferroelectric tunnel field-effect transistor” was published by researchers at Lund University in Sweden. “Reconfigurable transistors ...
