heterodyning

Using an electronic circuit to combine an input radio frequency with one that is generated in order to produce new frequencies: one that is the sum of the two and another that is the difference of the two. Heterodyning is typically used to bandshift incoming frequencies into intermediate frequencies for demodulation. For heterodyning examples, see superheterodyne receiver.

My training instruction was more hands on used to teach and reinforce the skills necessary to operate and maintain the R-390A/URR general coverage HF receiver that uses super heterodyne principles (for example).
