IPC: H04L27/00
Filed: 1981-12-21
Abstract: PURPOSE:To detect the level of a digital sine wave easily through circuit constitution which eliminates the need for a filter, by finding the sum of and the difference between the input sine wave and its specific-time delayed output, and then summing up their square values. CONSTITUTION:A sine wave is inputted to an input terminal 7 and a delay circuit 1 delays the wave by a specific time when a prescribed relation exists between the frequency of the input digital sine wave and a sampling frequency. As adder 2 adds the input signal to the terminal 7 to the output 8 of the circuit 1. A subtracter 3 finds the difference between said input signal and the output 8. The output 9 of the adder 2 and the output 10 of the subtracter 3 are squared by squaring devices 4 and 5. The outputs of the squaring devices 4 and 5 are summed up by an adder 6, which outputs the square value of the maximum level of the input digital sine wave to its output terminal 13. Thus, the simple hardware constitution provides accurate level detection.
