IPC: H03F1/32
Filed: 1981-08-25
Abstract: PURPOSE:To reduce distortion by simple circuit constitution without using a negative feedback loop by amplifying a differential signal between an input signal and a signal of common electrode and adding this to the other side of resistance connected to the common electrode and output electrode side. CONSTITUTION:An input signal e1 is applied to the input electrode of an amplifier element 2 and a resistance 3 is connected to a common electrode. A differential signal e2 between the input signal e1 and a signal generated in the common electrode is amplified by, for instance, a differential amplifier circuit 4. The amplified signal i2 is added to both or one of other end of resistance 3 connected to above-mentioned common electrode and output electrode side to cancel distortion components generated from the amplifier element 2. For instance, a circuit shown in a figure in which FET is used as an amplifier element 2 is used, and resistance value R3 of the resistance 3 is so selected that an expression i2/e2=1/R3 holds to cancel influence due to level between gate source of FET2.

Title: Error compensating method for digital audio signal
Inventor: HAMAMOTO YASUHACHI
IPC: H04B14/04
Filed: 1993-06-03
Abstract: PURPOSE:To eliminate the sense of incompatibility with error generation by performing compensation with zero value replacement when error is generated continuously in over the prescribed number of frames. CONSTITUTION:When there is no CRC error, there is no processing at a preceding value replacement compensating circuit 14 and a zero value replacement compensating circuit 16, and decode processing is performed at an MPEG audio decode part 18. When no error in the preceding frame is decided, the data of the preceding frame are outputted as the data of the frame, in which this error is generated, by the circuit 14. When the presence of error in the preceding frame is decided, data '0' are outputted as the data of the frame, in which this error is generated, by the circuit 16. Thus, when error is singly generated in one frame, preceding value replacement compensation is performed and when error is generated continuously in over two frames, zero value replacement compensation is performed for frames following the second frame.
