Abstract

PURPOSE: To impart tones to scale signals by feeding the output of a mutiplexer to a multiplex variable filter so that the frequency characteristics of the filter may be varied in accordance with the multiplex conrol signals.
CONSTITUTION: The scale voltages VK1, VK2 and VK3, which correspond to throo scale signals I1, I2 and I3, respectivley, are subjected to time-shearing multiplexation by a multiplexer 18 and then are fed through a voltage converter 15-1 to an adder 21. A main voltage Vcc is fed through an attenuator 17-1 to the adder 12. A multiplex variable filter 100 has its control resistor 35 supplied with a voltage 2 which control the intensity of resonance. This voltage 2 is sufficient to be common for the respective scale signals so that similar results can be obtained to the multiplexation without the use of the multiplexer. Envelope signals G1, G2 and G3 are subjected to the time-shearing multiplexatin by means of a multiplexer 42 so that multiplex control signals MG are fed to a control resistor 40
