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 original heterodyne detector was pioneered by Canadian inventor Reginald Fessenden
in 1905, but it was not pursued far. The vacuum tube electronic oscillator would not arrive
until 1912. The autodyne receiver, which has one stage function as both a local oscillator
and a heterodyne mixer, had several inventors around 1912 to 1913. The superheterodyne
principle was revisited in 1918 by U.S. Army Major Edwin Armstrong in France during
World War I.
On Receiver: Open receiver There is a Jumper called Learn Short for 1 second. (Use jumper or Screwdriver) Remove jumper/screwdriver led on receiver switches on. On Remote/Transmitter: Press the button required for that receiver. Led goes off on receiver after a few seconds Push same button selected on remote again. The led will flash on receiver. Procedure complete.
can a superheterodyne receiver generated high noise
A local oscillator is a device that generates a sinusoidal signal with a frequency such that the receiver is able to generate the correct resulting frequency, or intermediate frequency (IF), for further amplification and conversion into audio detection. There is one local oscillator in a single conversion super heterodyne receiver where heterodyning or mixing is used to generate beat frequencies, which may be the sum or the difference of two frequencies. The local oscillator is usually adjustable and in step with the increment or decrement in the receiver frequency. For instance, if the receiver is tuned to 1,455 kilohertz (kHz) as radio frequency input (RF-in), the local oscillator frequency (LOF) may be set to 1,910 kHz for a so-called high side injection. The two signals are fed to an electronic device known as the mixer, which derives LOF - RF-in = IF or 455 kHz, which suggests why amplitude modulation (AM) broadcast receivers have about four stages of low-power amplifiers tuneable to 455 kHz.
It is the ability of aradi receiver to deliver acostant amount of outpu during a given interval of time.

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.
