Definitions

  • sequentially readout voltages constitute a waveform of a particular tone color or an envelope of a particular shape.
  • the decoder and the reading switch circuit may be formed by MOS transistors, and the circuits thus formed may be combined together with the resistance layer in an integrated structure on the semiconductor substrate.
