Filed: 1989-07-13
Abstract: PURPOSE:To enable high accuracy processing even to a wide band signal by supplying input data through an infinite response digital filter to a table, where a non-linear characteristic is written, and adding the output data of this table to the input data. CONSTITUTION:An input digital filter (x) is supplied to an IIR filter 1 and only the high area component of the signal is passed. An NLT 2 is a ROM wiring in the table to output data, for which the logarithmic compression of these data is executed corresponding to the input data, and a high area component (w) of a video signal, for which non-linear amplitude compression is executed, is obtained by the NLT 2.

IPC: H03K17/62
Filed: 1986-08-01
Abstract: PURPOSE:To share a single amplifier and to decrease the number of elements by performing the ON/OFF switching actions of an output circuit at an output buffer stage. CONSTITUTION:An NPN transistor TR9 and a resistance 24 are added to a conventional output circuit consisting of a PNP TR4, an NPN TR8 and resistances 20 and 22. Then the output circuit is turned on and off. When the voltage V15 of a terminal 15 exceeds the base voltage VB8 of the TR8, a current satisfying IE9=V9-8/V24 flows in accordance with the difference V9-8 of emitter voltage between both TR9 and 9. Then IE9>>I16 is satisfied when the V15 has a sufficiently high level and the output circuit is turned off. In other words, the output circuit can be turned on and off by the voltage V15. Thus, an amplifier of a single input and multi-outputs can be shared by all output systems and therefore the number of elements can be decreased.
