ABSTRACT:
A directional microphone system gain adjusts the sum of signals that are received from two microphones mounted spaced apart. The gain adjustment is generally proportional to the product of the two microphone signals. Analog multipliers are used both for multiplying the signals together and also to form a gate that gain adjusts the sum of the signals. Microphone arrays can increase the directionality of this system, and can permit electronic steering.
