Product description
Virtually all modern radios use the superhet principle. It offers many advantages over other types of radio receiver. However, these radios can be fairly complicated, as can the specifications used to define their performance.
This handbook explains the operation of the superhet in understandable terms. It also explains the specifications likely to be encountered so that anyone looking to buy a radio can assess its performance, be it a short wave communications receiver, a world band radio or a scanner.
Topics covered in the book include: introduction and historical perspectives, basic concepts, sensitivity and overload, selectivity, local oscillator, demodulation, and operations.
Contents: Introduction and history; sensitivity and overload; selectivity; local oscillator; demodulation; operation
112 pages paperback
