Frequency modulation (FM) is the method of conveying informations over a carrier wave by varying its frequency .This is different from the Amplitude Modulation (AM) in which the amplitude of the ...

Modern society is definitely more mobile than it was several decades ago. Accompanying the increased mobility is a corresponding craving for greater quantities of information. The increased demand has ...

This year, we recognize John R. Carson for two major contributions to communications technology: the invention of single-sideband (SSB) modulation and his rule for estimating frequency modulation (FM) ...

The term FM is slightly misleading because it stands for Frequency Modulation, a technique to broadcast radio waves. The frequencies between 80MHz to 110MHz, generally used to broadcast FM across the ...

In the Dec. 7 issue of RWEE, we asked: What is a Bessel function and what is a typical application? a. A numerical description of propagation through a solid body, most often used in coax design. b. A ...

The diagram utilizes two BC548 transistors, more importantly descent results although not as good as RF transistors which provide high performance at wide bandwidth. It also utilizes electret ...

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, ...

(1) An earlier magnetic disk encoding method that places clock bits onto the medium along with the data bits. It was superseded by MFM and RLL. FM radio was invented in the early 1930s by Edwin Howard ...
