A superheterodyne receiver is a Radio Frequency receiver method that multiplies the received signal frequency with a local oscillator frequency to get frequencies that are the sum and difference of the 2 frequencies. For example, if the received signal is 5MHz and the local oscillator frequency is 4MHz, they are multiplied together. 1MHz and 9MHz frequencies would be gotten. Usually the 1MHz is the Intermediate Frequency (IF). It will be admitted (through a band pass filter) later passed through the required electronic circuits for proper processing. There is also the method of the Variable Tuned Filter.

The discriminator, and the ratio detector, perform the same function in an f.m. receiver as the detector does in an a.m. receiver, i.e. it recovers the modulation.
fidelity of a receiver is its ability to produce accurate output over a range of frequencies.
Switched power means the AC power will be lost if the receiver is on standby. In unswitched, the power will be supplied even if the receiver is on standby. Regards, Raghu
A crystal receiver will pick up radio signals within a close range. One must use headphones to hear the signal, as it is generally very weak. A crystal receiver does this without the use of electricity or batteries.
its a radio! :D

Het is short for heterosexual, heterogeneous, or even heterodyne.

Perhaps this will help? http://en.wikipedia.org/wiki/Heterodyne
I persume you mean the Giant Meterwave Radio Telescope (GMRT) in India. The way a received signal is processed is equivalent to the working principle of a double-super-heterodyne-receiver. That means that a received signal is filtered, mixed with another frequency and filtered again to downscale it for transport from telescope antenna to the observation room...here it is mixed and filtered again so that the signal is be downconverted for recording and data analisys.
