Many people think old AM transmitters are worthless. If a high-level, plate-modulated tube transmitter is replaced by a shiny new solid-state transmitter, why should the old one be kept? Heck, you ...

Abstract An experimental frequency modulated transmitter is described, giving a power output of 1 kW. It was originally designed to operate in the band 40-50 Mc/s, but by the addition of a ...

Shifting the phases also changes the frequency, so [nckm] can receive this audio signal with the FM transmitter on his phone. Is this really phase modulation if it’s being received by an FM radio?

Editor's Note: This is a multi-part excerpt from Agilent Technologies' Application Note: Mobile WiMAX PHY Layer (RF) Operation and Measurement. Part 1 of this article introduces the WiMAX standard and ...

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 ...

IN the United States, frequency-modulation has been assigned the wave band 42-50 m.c and at these frequencies, simplification in design and reduction in size of transmitters are of particular ...

There are many different varieties of modulation but they all fall into three basic categories, namely amplitude modulation, frequency modulation and phase modulation, although frequency and phase ...

Puducherry station of All India Radio (AIR) today commissioned a state of art new 10 Kilo Volt transmitter installed at a cost of Rs 2.25 crores.

Sweat-reduction factor The first part of a transmitter rebuild project is to test the transmitter and make repairs necessary to get it running to factory specifications on the original frequency into ...
