The circuit was designed to operate a voice transmitter over the AM medium wave band under a limited power output. Amplitude Modulation – a method or technique of emphasizing and transmitting data or ...

Most often ultrasonic transducers are used for distance measurements, and in the DIY world, usually as a way for robots to detect obstacles. But for a weekend project, [Vinod.S] took the ultrasonic ...

The author, WA2EWT, is a broadcast consultant in St. Petersburg, Fla. The FCC has formally approved a “green” technique for AM radio stations that want to reduce their operating costs. The technique ...

The mode of operation of the amplitude-modulated transmitter Class-C output stage is discussed, with particular references to the case where the load impedance varies over the working frequency band; ...

Three innovative design techniques substantially enhance wireless transmitter performance and can boost power efficiency and elevate data rates concurrently. This effectively aligns with the growing ...

Two things have been overlooked with phasing amplitude modulation. One is the importance of pulse modulation; the other is that logic gates can be used for analog signal processing. Both of these ...

Here’s a question: when did you last listen to an AM radio station? If your answer is “recently”, chances are you are in the minority. You might ask: why should you listen to AM? And you’d have a ...
