Abstract: 1380714 Illuminated effects P S VOGEL 15 Nov 1971 [17 Nov 1970] 52987/71 Heading A6M [Also in Division H4] An arrangement for producing a visual pattern on a television CRT tube in response to the frequency components present in an audio signal employs a number of audio-frequency band-pass filters the outputs of which control separate "effect generators" to produce video signals. The presence of an output from a filter may:-(1) be utilised directly as a luminance or chrominance signal; thus mid-frequencies appear as horizontal bars; (2) be rectified (smoothed) and supplied to give an overall flash; (3) be used to modulate a video signal of a few hundred KHz from an oscillator running at a multiple of line frequency to produce vertical bars; the frequency of the oscillator may be modulated to give the bars a wavy appearance.  Fig. 2 shows an arrangement in which the outputs of two square-wave oscillators at different frequencies are logically combined in various ways to produce signals capable of generating the patterns shown; the five outputs are each provided with a gate opened in response to an output from a band-pass audio filter. The use of ramp instead of square-wave signals is described in connection with the production of bar signals of varying width, and also enabling diamond patterns by combining line- and frame-frequency signals. The video signals produced may be modulated onto a carrier for feeding to a TV aerial input.
