Kenya has been using analogue radio, which uses either amplitude modulation (AM) or FM. FM is adopted widely because it gives ...
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, ...
Spread spectrum clocking (SSC) is used in many computer interfaces such as PCI Express and Serial ATA to improve the EMI performance of the interface. It takes the form of frequency modulation (FM) of ...
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 ...
(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 It was superseded by MFM and RLL.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 ...
A 50-MHz FM signal is desired to have a frequency deviation of 24 kHz. The output of early stages of the transmitter is a 5-MHz signal with a frequency deviation of 4 kHz. How can the desired output ...
