Product Detector - A Simple Product Detector

A Simple Product Detector

The simplest form of product detector mixes (or hetrodynes) the RF or IF signal with a locally derived carrier (the Beat Frequency Oscillator, or BFO) to produce an audio frequency copy of the original audio signal and a mixer product at twice the original RF or IF frequency. This high-frequency component can then be filtered out, leaving the original audio frequency signal.

Famous quotes containing the words simple and/or product:

    You are all alike, you respectable people. You can’t tell me the bursting strain of a ten-inch gun, which is a very simple matter; but you all think you can tell me the bursting strain of a man under temptation. You daren’t handle high explosives; but you’re all ready to handle honesty and truth and justice and the whole duty of man, and kill one another at that game. What a country! What a world!
    George Bernard Shaw (1856–1950)

    For man is not the creature and product of Mechanism; but, in a far truer sense, its creator and producer.
    Thomas Carlyle (1795–1881)
