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 ...

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 ...

The author is a consulting broadcast systems engineer. Electricity constitutes a major part of the operating expenses of analog transmitter sites operating below 30 MHz, if not the largest. This is ...

There was a time — not long ago — when radio and even wired communications depended solely upon Morse code with OOK (on off keying). Modulating RF signals led to practical commercial radio stations ...

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 ...

The proposed CORDIC-less digital polar transmitter demonstrates superior power added efficiency (PAE) and system efficiency (SE) for similar modulation signals. It also supports wider bandwidths, ...
