1. What is the CMRR of a 741C at 100 kHz? The MPP value when the load resistance is 500 V? The open-loop voltage gain at 1 kHz?
2. What is the initial slope of a sine wave with a frequency of 15 kHz and a peak value of 2 V? What happens to the initial slope if the frequency increases to 30 kHz?
Desing a combinational circuit that accept a 3-bit numbuer and generates a 6-bit binary number output equal to the squre of the i/p number.
A signal x(t) can be represented as x(t)=xe(t)+xo(t) where xe(t)=(1/2){x(t)+x(-t)} is the even part, and xo(t)=(1/2){x(t)-x(-t)} is the odd part of the signal. Let x(t) be an energy signal with an energy of 20 Joules. Suppose the even part of x(t) is..
Figure 13-34 shows the graph of the voltage across an inductance. The current changes from 4 A to 5 A during the time interval from 4 s to 5 s
1 Derive the output voltage across the series circuit as a function of time in standard form. 2 Convert the output voltage to laboratory form. 3 Convert the output voltage to exponential form. 4 Derive the average power delivered to the resistor in o..
Draw an inverting amplifier using an op amp with component values. Now, tell me where the virtual ground is. What are the properties of a virtual ground? What is the closed-loop voltage gain, input impedance, and bandwidth?
What is the minimum bandwidth needed to achieve a data rate of 8 bits/ second if the signal is transmitted using NRZ, MLT-3 and Manchesster encoding
A president, secretary, and treasurer are to be chosen from a group of 10 senior members of the IEEE student chapter at the Citadel. Assume that each member cannot serve more than one position. How many different choices of officers are possible
Develop a sequential circuit with a single data input S and a single data output Y. The output is 1 when the input value in the current clock cycle is different from the input value in the previous clock cycle, as shown in the timing diagram in Fi..
A 1000KVA transformer is at full load with a 0.5 lagging powerfactor. If the line voltage is 500 volts at 60Hz. Find the New Volt-Ampere quanties needed to improve the power factor to 0.95 by adding capacitors in parrallel with the transformer.
What type of material belongs to reflection spectrum A, what type to B? (Justify). Note the scale difference!
A microphone of 300Ω impedance has an output at -60 dB below a 1 mW reference level. The microphone provides input to an amplifier which in turn is to provide an output level of 30 dBm when a load of 8 Ω is connected to the output terminals of the..
The system operates properly when exactly one of the sensors has its output equal to 1. An alarm must be raised when two or more sensors have the output equals to 1. Design the simplest circuit that can be used to raise the alarm. Give the cost of..
