Title: Sound receiver
Inventor: NAKAHARA HITOSHI
IPC: H04N5/60
Filed: 1989-05-09
Abstract: PURPOSE:To realize channel mixing with high accuracy with simple configuration without necessitating adjustment for a component by multiplying the voice signal of a mixing channel by specific times with a digital circuit consisting of a bit shifter and a subtractor, etc., and adding it on the voice signal of a mixed channel. CONSTITUTION:When a channel mix signal is inputted from a terminal 3, a switch 30 is closed, and a switch 31 is connected to an upper side. A signal of CH3 is multiplied by 1/4 with a two-bit shifter 36, and is inverted at an inverter 37, and is added on an original signal at an adder 38, and the output of the adder 38 goes to a signal of 3/4 times the original signal of CH3, and is added on a CH1 and a CH2 at adders 32 and 34. Similarly, a signal of CH4 multiplied by 3/4 at adders 33 and 35 is added on the CH1 and the CH2. Therefore, the signals of CH1 and CH2 on which the signals of CH3 and CH4 multiplied by 3/4 are added are outputted to output terminals 42 and 43, respectively. In such a way, it is possible to realize the channel mixing with a few number of components without necessitating the adjustment, and whose stroke is hard to deteriorate.
