Figure P2.46 shows a circuit for an analog voltmeter of very high input resistance that uses an inexpensive moving-coil meter. The voltmeter measures the voltage V applied between the op amps positive-input terminal and ground. Assuming that the moving coil produces full-scale deflection when the current passing through it is 100 A, find the value of R such that full-scale reading is obtained when V is +10 V. Does the meter resistance shown affect the voltmeter calibration?

Module 3 D : Clocked Synchronous State Machine We are going to talk about two different state machine structures known as Moore and Mealy Machines. State machine is a generic name given to sequential circuits. CLOCKED indicates that the flip flops employ a clock input. Synchronous meaning that all the flip flops change state together. Analysis means to analyze the behavior using steps : constructing the PS – NS equations, drawing the state transition diagram and the timing chart. State Machine structure consists of three blocks : 1) Next state logic – combinational circuity that provides the excitation necessary to transition to the next state based on the current inputs 2) output logic -- combinational circuitry that uses the current state to determine th
