Frequency modulation is also more robust against simple signal amplitude fading phenomena.FM receivers employ a special detector for FM signals and exhibit a phenomenon called Capture effect, where ...

Figure 3-1. An alternating waveform. Amplitude modulation Possibly the most obvious method of modulating a carrier is to change its amplitude in line with the modulating signal. The simplest form of ...

You need to FM modulate the carrier. [Vinod.S] did the music playback in the usual way and fed the analog signal via a resistor to the crystal.

Overcoming conventional technological limitations to realize high-speed optical coherence modulation at 350 kHz. Structured ...

By analyzing signal characteristics like frequency hopping patterns, bandwidth, and modulation schemes, an SDR can detect the presence of nearby drones, even those attempting to operate discreetly.

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’ ...

The 531N supports the extended FM range 76 MHz –108.1 MHz in 100 kHz increments along with 110/220VAC power supply for worldwide distribution. All front-panel functions are now as close as a laptop, ...

We are featuring the products that won the Radio World Best of Show Award at the recent NAB Show. Winners were chosen by a panel of radio engineers and RW editorial staff for their innovation, feature ...

KRPE-LD San Diego, low power TV channel 6, atop Mt. San Miguel, is the first station in its market to broadcast ATSC 3.0. The FCC granted a Special Temporary Authorization (STA) for a signal on TV ...
