Q. No. 1:
Explain concept of stiffness. What are the conditions for maximum power transfer in an instrumentation? Obtain transfer function of the following circuit.
Q. No. 2:
What is meant by dynamic response? Obtain (derive and plot) unit step input response of a generalized second order measurement device.
Q.No.3:
Explain the concept of dead time. A first order measurement device has following open loop transfer function. _
x- -is
Derive and plot its open loop time response for the unit step input.
Q. No. 4:
Write technical notes on the following. Support your answer with neat sketches and relevant details.
(a) LED and LCD
(b) Fiber Optical Sensor
Q. No. 5:
What are discrete data systems? Mention an example of it with suitable sketches. Obtain Z-transform of analog signal f (t + nt).
Q.No.6:
Explain narrow band pass filter (op-amp based) using multiple feedback. Derive and obtain its transfer function.
Q.No.7:
Write a Fourier series approximation for the function as given below, such that the error is zero at t 0, T/3, T/2, 2T/3 and T. Draw the approximate function thus obtained. If this function is used as an input signal to a second order instrument with = 10 rad/sec, = 0.3, K* 5 mV/mm, find the steady state output of the instrument. (All notations carry standard meaning.)
