A) With the P1 we regulate the intensity of sound. B) With the P2 we regulate the frequency of reception. C) Optionally: If you want to check the frequency with your PC it will be supposed you make ...

Michel Durr, Analog & RF Imaging IC Design Program Manager talks to AZoNano about impulse radio ultra-wideband circuits for measuring distances within centimeters of accuracy. BeSpoon, a fabless ...

For the first time in history, a prototype radio has been created that is claimed to be completely digital, generating high-frequency radio waves purely through the use of integrated circuits and a ...

Full-duplex radio communication usually involves transmitters and receivers operating at different frequencies. Simultaneous transmission and reception on the same frequency is the Holy Grail for ...

A simple fm radio transmitter circuit which covers frequencies from 88 to 108 MHz. It is built with 3 transistors: BC109, BFR91A and BFR96S. It is quite stable and the output power is around 200 mW.

In writing articles about vintage radio, I try to alternate between the technological and the people who made the technology possible. Occasionally, I just feature an interesting radio and the story ...
