Since then, until quite recently, the Superhet design has been at the heart of a majority of commercial radio receivers. Direct Conversion Receivers were devised around 1930, but required ...

In RF design, we refer to multipliers as frequency mixers. In a superheterodyne receiver the desired RF signal is multiplied down to an intermediate frequency (IF) by use of a mixer and a variable ...

The carrier frequencies for AM operate from 530 kHz to 1610 kHz. Many superheterodyne AM radios use a demodulation circuit designed for 455 kHz. When the listener tunes in a station, an oscillator ...

the homodyne receiver was one of the earlier methods of building radios, both of which were superseded by the superheterodyne approach. See superheterodyne receiver. THIS DEFINITION IS FOR ...

We will use this hypothetical receiver as the basic generic framework for evaluating receiver performance. The design in Fig. 9-1 is called a superheterodyne receiver and is representative of a large ...

To prevent the possible image interfering with the desired signal and other strong unwanted signals jamming the superheterodyne receiver, sufficient filtering before the frequency converter is usually ...
