    Hi

    I need a schematic circuit for the following problem:

    The equivalent circuit of a transducer that measures the speed of a motor is a current source in parallel with an output resistance. The current source produces an output current of 1μA per revolution/second of the motor and the output resistance is 50kΩ. Design a discrete transistor circuit that produces a full-scale output of 10V for a maximum motor speed of 60 revolutions/second. The nominal transistor current gain is β = 100 with tolerances of ±30%. The accuracy of the output signal is to remain within ±1%. Pls help. Thanks.

    Hello,

    Is this a home-work or college assignment?
    If so, what hava you already calculated for the transducer.
    Must the amplifier be made with a transistor or is an opamp also allowed?

    Hi

    This is a college assignment. The amplifier must be made with transistor only. As I don't know how to get started, I am not able to make any calculation for the transducer.
