Engineering Instrumentation 01. a) Describe the function of a filter circuit, in general terms. b) Derive the gain of the circuit in Figure 1. Vin] - C' I Va" Figure 1 02. With reference to the circuit above (Figure 1), explain its function with a diagram. 03. Draw a circuit that will perform the opposite function of the circuit in Figure 1, derive an expression for its gain and explain its operation. 04. Write down 4 characteristics of an ideal operation amplifier (OP-AMP) and describe how the characteristics of an ideal operation amplifier (OP-AMP) differ from those of a real OP-AMP. 05. Draw the circuit diagram of an inverting amplifier using operation amplifier (OP-AMP) and derive its gain. 06. A 440 V shunt-connected DC motor has an armature resistance of 0.8 (2 and a field resistance of 200 (2. Determine the back e.m.f when giving an output of 7.46 kW at 85 per cent efficiency. 07. Sketch the Torque: Speed graph for a DC motor and use it to obtain expressions for the motor starting torque and the motor no-load speed in terms of motor parameters and the supply voltage, neglecting friction effects. 08. A permanent magnet DC motor has an armature resistance of 0.5 Q and when a voltage of 120 V is applied to the motor it reaches a steady-state speed of rotation of 20 rev/s and draws 40 A. What will be (a) the power loss in the armature and (b) the power input to the motor? 09. A 12-bit DA converter has a step size of 10 mV. Determine the full-scale output voltage and the percentage resolutions. 10. A certain 8-bit AD converter has a Full Scale input of 2.55 V (Le, VA = 2.55 Vproduces a digital output of 11111111). It has a specified error of 0.1% Full -Scale. Determine the maximum amount by which the V‘Ur (D/A converter output) output can differ from the analogue input.
