Understanding the Methods of Frequency Modulation The primary function of a frequency modulation generator is to produce a carrier with variable output frequency. The frequency variation is proportional to the instantaneous values of the modulating voltage. The other requirements are the un-modulated car......
XM Radio: Understanding How Radio Waves are Generated There are two types of devices in which it may be necessary to generate amplitude modulation. The first of these is, the amplitude modulation transmitter generates such high power that its prime requirement is efficiency, so quite complex means of amplitu......
The Down and Dirty on How Amplitude Demodulation Works The process of detection or demodulation consists in recovering the original modulating voltage from the modulated carrier voltage. Thus detection is a process of reverse modulation. The modulation frequency terms which were translated to higher part of t......
The Stages of Super Heterodyne Receivers. There are different stages of a super heterodyne receiver namely antenna or aerial, radio frequency amplifier, frequency converter stage, intermediate amplifier stage, second detector, audio frequency amplifier and loud speaker.
An aerial intercepts t......
Radio Frequency Amplifiers There are many similarities between radio frequency amplifiers and audio frequency amplifiers, but there are also many differences. Radio frequency amplifiers perform the same amplifying functions at radio frequencies as do audio frequency amplifiers at a......
