Instead, the volume is controlled by pressing UP and DOWN buttons. Simple, low component count tone generator. The attenuator, a simple voltage divider, is constructed using resistor R1 and an N-channel MOSFET, Q2. Those who know him well are allowed to call him "Pot". The reverse of the digital demultiplexer is the digital multiplexer 1 to 4 demultiplexer A 1 to 4 multiplexer uses 2 select lines (S0, S1) to determine which one of the 4 outputs (Y0 - Y3) is routed from the input (D). This can be used as a digital volume controller for audio amplifiers and other applications. The integrated circuit includes a USB controller for A / D and D / A converter, HID part for 3 buttons, volume control, custom converters and S / PDIF encoder and decoder. Volume 04—Circuit Protection: 4/11/2019 11. These devices are fitted with mechanical components that react to changes in the downstream air pressure.
