If a 10Ω rheostat is added in series with the bias resistor in Figure 14-56, what are the minimum and maximum voltage gains?
A mealy sequential circuit has one input (x) and one output (z). Z = 1 if and only if the most recent input, combined with the preceding 3 inputs, was not a valid BCD encoding of a decimal digit; otherwise, z = 0.
A single-phase load is supplied through a 35-kV feeder whose impedance is 95 + j360 ohm and a 35-kV:2400-V transformer whose equivalent impedance is 0.23 + j 1.27 ohm referred to its low-voltage side. The load is 160kW at 0.89 leading power factor..
A second-order bandstop filter is required to satisfy the following specifications: fs= 8,000 Hz f0= 60 Hz bandwidth= 40 Hz Find the transfer function and difference equation by the pole- zero placement method.
Problem: A three-phase, 35kW, 400V, 50Hz induction motor operates at full-load with an efficiency of 87.5% and at a power factor of 0.8 lagging. Using the power triangle approach:
Design a suitable amplifier using a combination of these stages. Your design should utilize the minimum number of stages and should ensure that the signal level is not reduced below 10 mV at any point in the amplifier chain.
What happens if R was infinite in parallel RLC circuit and What happens if R was zero in parallel RLC circuit what will be the circuits can we still apply the neper frequency now which will be zero
A potentiometer is used to measure the position of a shaft. theinput range of shaft position is from - 160o to +160o . the corresponding output range is from -20 to +20 v. what is the span of this position sensor
An electric pencil sharpener is rated 240 mW, 6 V is connected to a 9-V battery and a series-dropping resistor Rx needed to power the sharpener. Calculate the value of the series-dropping resistor Rx needed to power the sharpener.
A DC motor has the following parameters: Number of armature conductors = 60, length of rotor = 30 cm, radius of rotor = 10 cm, field flux density = 1 T, armature resistance = 1.2-ohm. Neglect the armature inductance. The maximum armature current r..
Two coils A and B are mutually coupled so that 55% of the flux of Coil A links Coil B. It is found that current of 2A produces a flux of 0.04 mWb in coil A while the same current in B creates in it flux of 0.05 mWb. If Number of turns are 1000 and 13..
A standard 12-V car battery has an ampere-hour rating of 30 Ah, whereas a heavy-duty battery has rating of 51 Ah. Calculate the ratio of available energy and the percentage increase in available current for starting.
