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, ...

Last month we looked at contributions to the art made by amateur operators, in particular advancements in Amplitude Modulation, or AM, and how it came to give radio its voice. This month, we will look ...

The average textbook definition of modulation reads: modulation is a process in which the frequency, phase or amplitude of a carrier wave varies in step with the instantaneous value of the modulating ...

“There is nothing new under the sun” is a phrase proclaimed in Ecclesiastes. We are at the brink of converting radio and television broadcasting over to digital yet the theories behind these systems ...

Note: we are working to recover the figures for this article. The process of designing a short-range radio system can be complex and often involves many project tradeoffs (Fig. 1). With a little ...

The circuit was designed to function on the middle of the FM band, 98 MHz, since the FM frequency ranges from 88 MHz to 108 MHz. Transmitter – an electronic device that can produce or amplify a ...

It marked the beginning of the end of an era. In January, Norway began transitioning from analogue to digital radio broadcasting (DAB). This means that FM radio broadcasting infrastructures across the ...

FM, which stands for Frequency Modulation, is one of the radio broadcasting systems in the UK. FM uses frequencies from 87.5 MHz to 108MHz. The BBC broadcasts a number of UK-wide network services e.g.

"The continuous good fortune which has followed me, providing second chances at inventions when the first chance was missed and tossed away, has been all that a man could hope for and more than he has ...

(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 It was superseded by MFM and RLL.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 ...
