What is a super heterodyne receiver?

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

What is the fidelity sensitivity and selectivity of a receiver?

These are the 3 criteria in choosing a good receiver. Sensitivity refers to the ability of the receiver to receive very weak signal. Selectivity to select the desired frequenc

Do you connect speakers to receiver or amplifier?

Depends on what your definition of "receiver" is, but most of the time - to the amplifier. Consider: if the receiver is some form of a device that receives some signal,

Working of single stage amplifier?

A simple, 1 transistor single stage amplifier can be made using several resistors to bias a NPN or PNP transistor into its' linear operating region. With this done, a small vo

Why super heterodyne radio receivers are called 'super'?

When two frequencies are "mixed" the sum and the difference frequencies are produced. These frequencies are called heterodynes. If these frequencies are outside the range of h

What is the difference between an amplifier and a receiver?

An 'amplifier' usually refers to an audio amplifier for a HiFi stereo system. (Although amplifiers are used in other devices, such as Radio transmitters, and is an electronic
