专利汇可以提供Gated compressor, distortionless signal limiter专利检索，专利查询，专利分析的服务。并且A distortionless gated compressor for limiting the amplitude of a signal so as not to produce undesired signal levels responsive thereto is disclosed. The gated compressor includes a distortionless multiplier which multiplies an AC signal from a factor defined by a DC control signal. The compressor includes a plurality of channels each responsive to a signal produced in response to the multiplier''s output. As long as the signal, supplied to any channel, does not exceed a selected level for the particular signal, the output of a multi-input OR gate is constant, thereby resulting in the supply of a constant DC control signal to the multiplier. However, when the signal supplied to any channel exceeds a prescribed level, the level of the DC control signal is reduced to reduce the multiplier''s output level and thereby prevent the signal applied to any channel from exceeding its prescribed level.，下面是Gated compressor, distortionless signal limiter专利的具体信息内容。

权利要求

1. A signal compression system comprising: a source for providing a variable amplitude signal; control means for providing a direct-current control signal; a multiplier for providing an output whose amplitude is a function of the product of the amplitude of said first signal and the amplitude of said control signal; and channel means coupled to said control means and including n channels, each channel being responsive to a different input signal, said channel means further including gating means for controlling said control means to vary the amplitude of said control signal from a selected amplitude only when the input signal to any of said channels exceeds a preselected level associated therewith, n being an integer not less than two, the magnitude by which the amplitude of said control signal is varied from said selected amplitude being directly related to the largest difference by which the input signal to any of said channels exceeds the preselected level associated therewith.

2. A signal compression system as described in claim 1 wherein said first signal is an alternating-current signal.

3. A signal compression system as described in claim 2 wherein said channel means includes an n-input OR gate which provides a constant amplitude output as long as none of the signals applied to said n channels exceeds the preselected level associated therewith, with said OR gate providing an output which varies in amplitude in direct relation to the largest increase of any of said input signals above its preselected level.

4. A signal compression system as described in claim 3 wherein each of said channels includes an AC to DC converter and said OR gate includes a reference diode and n control diodes each associated with a different channel, with all of said control diodes being back biased as long as none of the input signals applied to said channels exceeds its preselected level.

5. A method of limiting the amplitude of an input signal to a device so that none of the signals produced therein exceeds a preselected amplitude level associated therewith, the steps comprising: supplying to said device a signal whose amplitude is equal to the product of the amplitude of a variable amplitude input signal and the amplitude of a control signal; monitoring at least two of the signals produced in said device, and reducing the amplitude of said control signal from a selected amplitude so as to reduce the amplitude of the signal which is supplied to said device whenever the amplitude of any of the monitored signals exceeds a preselected amplitude associated therewith, the magnitude by which the control signal amplitude is reduced from said selected amplitude being directly related to the largest amplitude difference by which the amplitude of any of the monitored signals exceeds the preselected amplitude associated therewith.
