Question 1 - Analogue Closed Loop Control Systems Many control systems involve processing analogue signals such as heat, light and movement Therefore analogue closed loop control system require walogue processing devices such as the operational amplifier (op-amp). One of the most common control applications involves using the op-amp as a comparator. In it's simplest form a comparator just compares two voltage signals, VI and V2. Ir VI is higher than V2 the output, Ve, is 'low', VI is lower than...
