Abstract
PURPOSE:To simplify the circuit of the titled divider and to make it inexpensive by constituting a divider of two channels by combining one of a low-pass filter circuit and a high-pass filter circuit with a subtracting circuit. CONSTITUTION:The titled divider is provided with a digital filter 11 of a linear phase type for extracting a prescribed frequency component from a digital signal appearing in an input terminal and supplying it to a first output terminal, and a subtracting circuit 13 for subtracting the digital signal on the first output terminal from that which has delayed the digital signal on the input terminal, and supplying it to a second output terminal. One of this filter circuit 11 is replaced with the subtracting circuit 13 of simple constitution. In such a way, the constitution of the whole circuit is simplified, and the cost can be reduced.
