The diagram utilizes two BC548 transistors, more importantly descent results although not as good as RF transistors which provide high performance at wide bandwidth. It also utilizes electret ...

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 ...

The average textbook definition of modulation reads: modulation is a process in which the frequency, phase or amplitude of a carrier wave varies in step with the instantaneous value of the modulating ...

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 ...

Frequency modulation (FM) is the method of conveying informations over a carrier wave by varying its frequency .This is different from the Amplitude Modulation (AM) in which the amplitude of the ...

Emerson, an industrial technology leader delivering automation solutions, has launched the world’s first native WirelessHART ...

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 doubling stage in ...

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; ...

Puducherry: 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. The transmitter of Frequency Modulation ...

Emerson has launched the world’s first native WirelessHART non-contacting radar level transmitter. The Rosemount 3408 Wireless Level Transmitter – Non-Contacting Radar aims to reduce the complexity, ...

The transmission standard for 4K8K satellite broadcasting ISDB-S3 has adopted 16APSK and 32APSK as new modulation schemes. 16APSK has been used for the 4K8K UHDTV broadcasting service in Japan since ...
