  time circuit
The accuracy of the live-time circuit of a 400-channel analyzer was studied in detail, and was found to be unsatisfactory even for long-lived radionuclides.
      
Adequate correction could be performed by feeding the information from the dead-time output of the multi-channel analyzer to an external live-time circuit with variable oscillator frequency and pulse-width.
      
As an example, consider the time circuit diagram shown in figure B1.
      
Both real time circuit switched speech traffic and non-real time interactive packet traffic is studied.
      
For instance, a switched capacitor DAC will be less sensitive to jitter than a continuous-time circuit.
