Superhet Receiver

This practical resource introduces the Superhet Receiver through a wide range of practical activities. Students investigate the principles and operation of a working superheterodyne receiver.

Practical tasks include the following:
  • Recognize the basic operation of a radio receiver
  • Identify the problems in channel selection
  • Measure the intermediate frequency (IF) and local oscillator (LO) frequency of a superhet receiver
  • Recognize the principle of operation of a superhet receiver
  • Examine the local oscillator
  • Explore the radio frequency (RF) amplifier
  • Measure tuned gain of an intermediate amplifier stage
  • Recognize the function performed by a multistage IF amplifier
  • Determine the need for automatic gain control (AGC)
  • Observe the operation of AGC

Please note that this resource requires access to either an Experiment Platform (409-01) or an Experiment Card Motherboard (409-02).
