Filed: 1979-05-23
Abstract: PURPOSE:To minimize the lowering of coding efficiency by removing a dummy code component, equivalent to the sum of the number of control code bits and that of error code bits, from a dummy code before framing. CONSTITUTION:Minimum code-length indicating circuit 9 outputs minimum code length X to comparing circuit 11.

When a coder outputs a coding end signal with signal line 12 held at logic ''1'', the output dummy code transmission permit signal of AND circuit 14 is output to a dummy code generating circuit to start the transmission of a dummy code. When value Y of counter 10 becomes equal to or greater than X, the output signal of circuit 14 becomes impassive and a dummy code transmission inhibition signal, the output of AND circuit 15, is output to a dummy code generating circuit to complete the transmission of the dummy code.

Filed: 1990-03-15
Abstract: PURPOSE: To obtain a small phase-modulated waveform by converting at least a part which is precedent to a numerical series into a corrected composite wave instead of the original number and extracting an analog waveform from the corrected composite wave by a reconstituting filter means. CONSTITUTION: A digital oscillator circuit 1 operates at a clock pulse speed for generating a series of (n)-bit numbers representing a cyclic analog waveform amplitude sample value. A subtracting circuit 2 subtracts each number from the precedent number and the obtained new (n)-bit number is applied to a converting circuit 3 so that the new number is converted into a composed waveform. The circuits 2 and 3 operate with a clock pulse set by a clock pulse generation source 6. An integrating circuit 4 extracts an analog waveform from the composed waveform and a limiter circuit 5 takes the square of the analog waveform so as to generate an output pulse of pulse generation frequency. Consequently, the mark/space ratio of the output pulse waveform can be made equal.
