Color video display for audio signals

DETAILED DESCRIPTION The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows: 1.
A chrominance generator circuit for a television receiver having three chrominance inputs, comprising: means for receiving an audio signal and generating a plurality of first electrical signals, each of the first signals being a function of the instantaneous amplitude of one portion of the total frequency band width of the audio signal; means, independent of said first signals, for generating a plurality of second electrical signals as a function of a pattern to be displayed on the television receiver; three modulators, each connected to receive at least certain of said first signals and at least certain of the second signals to produce output signals which have functions of these input signals; and means for providing the three modulator output signals to the three chrominance inputs of the color television receiver.
2.
The chrominance generator of claim 1 wherein said means for generating a plurality of second electrical signals which are a function of a pattern to be displayed on the television receiver comprises means for producing a plurality of digital signals having a unique time relation to the raster scan of the television receiver.
3.
The chrominance generator of claim 2 including an oscillator and a digital divider chain driven by the oscillator and connected to the raster scan generators of the television receiver and said means for producing a plurality of second electrical signals.
4.
The chrominance generator of claim 2 wherein said means for generating a plurality of digital signals having a unique time relation to the receiver raster scan includes an oscillator; a counter driven by the oscillator; and a summing network including resistances connected to various outputs of the counter.
5.
The chrominance generator of claim 4, further including capacitances interconnected to at least certain of the resistances to modify the rise and decay time of the voltages appearing at the output of the summing network
