  • Page 38: Theory Of Operation

    Vega’s C1616 8 Theory of Operation The C-1616 is a Digital Signal Processor (DSP) based product. Because of this, many of the signals that once could be probed on older products, are handled within the DSP itself. This would include DTMF generators and decoders, notch filters, tone generators and decoders, and all of the audio summing.

  • Page 39: Keypad/Display Board

    Remote Control Console The receive path also has a tie in to the transmit path. One of the taps on the TX transformers (T3 and T4) is fed to an Op-Amp stage that is then summed into the receive path Op-Amp. Gain set Potentiometers (R57 and R58) can be adjusted to change the relative TX Monitor levels.
