4-60DIFFERENTIATIONis the opposite of integration. In the differentiator, the output is taken across the resistor. Full differentiation takes place when the time constant of the circuit is 1/10 that of the input pulse. A COUNTING CIRCUIT receives uniform pulses, representing units to be counted, and produces a voltage output proportional to its frequency. ANSWERS TO QUESTION Q1. THROUGH Q27. A1. Negative. A2.
