1. Comparator
2. Fig. 3 Circuit of the experimental pulse comparator
3. screen dump demonstrates biasing a comparator with 240mV for a 2.45V reference source, using E24, alias standard 1% metal film resistors.
4. Therefore the photodetector generates a triangular pulse, which must be processed by a comparator to give a sharp rectangular pulse suitable for triggering the control unit.
5. When the output reaches 0V, the IC IC comparator switches, Q1 turns on, and the cycle repeats.
6. At that time, the IC IB comparator switches low, causing IC ID 'S bistable output to go low, which turns off Q1 .
7. Next month: In next month's Surgery we shall be describing a simple pulse repetition frequency comparator which can be used for synchronising the speed of two engines.
8. Our July Surgery provides information on how to detect the state of a contact breaker in a magneto, the circuit of an experimental pulse comparator, and a simple a.m. radio tuner.
9. The action takes place by way of a simple op.amp comparator, IC5, and transistor TR5.
10. Biasing a comparator with 240mV for a 2.54V reference source.
11. Finally, the pulse comparator arrangement shown in Fig. 3 has been provided as "food for thought".
12. A comparator with user-adjustable switching level is often incorporated in the encoder unit and small variations in the detected position can be obtained by adjusting this switching level.
13. The circuit shown in Fig. 2 (based on a comparator) will, however, detect changes in resistance of less than 0.1 ohm.
