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:

    I would like a simple life
    yet all night I am laying
    poems away in a long box.
    It is my immortality box,
    my lay-away plan,
    my coffin.
    Anne Sexton (1928–1974)

    Culture is a sham if it is only a sort of Gothic front put on an iron building—like Tower Bridge—or a classical front put on a steel frame—like the Daily Telegraph building in Fleet Street. Culture, if it is to be a real thing and a holy thing, must be the product of what we actually do for a living—not something added, like sugar on a pill.
    Eric Gill (1882–1940)
