Abstract

PURPOSE: To give singleness to a copied medium, improve productivity, and make a system general by subjecting a digitized acoustic signal and an analogue acoustic signal to FDM after subjecting them to FM.
CONSTITUTION: The original analogue acoustic signal is subjected to FM by coder 2 and is converted to transmission line code 71 and is applied to adder 11 through BPF 8. The analogue input signal is subjected to FM in 9 and is supplied to adder 11 through BPF 10 as signal 91. The FDM output of adder 11 is transmitted to transmission line 4 through limiter 12. In the receiving side, a desired signal is reproduced selectively.
