ELE 2003 Assignment 2.1 38. A tachometer connected to a motor is used to measure the rotation of the motor. tachometer produces 500V/rpm. The tachometer is then connected to two amplifiers cascade as shown below an inverting amplifier followed by a noninverting amplifier = 6 ko. and R2 = 12k for each amplifier VW a) The gain of the first and second amplifier? Gain = .. 12 = -2} & Gain = 1th = 1 + 1 2 3 = 3 b) If the motor is idling at 1000rpm what is the output of the cascade? c) If the output of the cascade is -7.5, what is the speed of the motor?
