A certain amplifier has an input voltage of 100 mV rms, an input resistance of 100kΩ, and produces an output of 10Vrms across an 8-Ω load resistance. The power supply has a voltage of 15 V and delivers an average current of 2 A. Find the power dissipated in the amplifier and the efficiency of the amplifier.
Given that the required transmission time for a block of data of length 64kilobits to be transmitted error-free is 6 seconds and that the receiver has a bandwidth of 20kHz, what is required SNR of the receiver
Design a combinational circuit that compares two 4-bit numbers to check if they are equal. The circuit output is equal to 1 if the two numbers are equal and 0 otherwise.
If we use the PC-relative addressing mode, and want to allow control transfer between instructions up to 50 locations away, how many bits of a branch instruction are needed to specify the PC-relative offset
What charge should be placed on the particle at position B such that the force on the particle at A is exactly zero.
Use a Spread Sheet or MATLAB or write a computer program to find the numeric solution to the conduction angle equation for a 60hz Half-Wave rectifier circuit that uses a filter capacitance of 100,000µf. The circuit is designed to provide 5v and 5a..
A proportional control system is to be used to control the wing flaps of a jet air-plane. The wind load is expected to cause as much as 600 in .lb of torque. The system should be able to keep the flaps to within 5 of the set point.
A flashlight bulb with a potential difference of 4.5 V across it has a resistance of 8.0 ohm. How much current is in the bulb filament?
Sketch the appropriate equivalent circuit and phaser diagram and, assuming step-down operation, determine (a) the magnetizing current and the core-loss component of exciting current; (b) the exciting current; (c) the no-load power factor; (d) the ..
How would you know a system is linear by just looking at its input/output characteristic graph And what does the sensitivity of a sensor tells us about the sensor
Find the Thevenin and Norton equivalent circuits for the circuit. Take care that you orient the polarity of the voltage sourceand the direction of the current source correctly relative toterminals a and b.
1. Compare a script tool such as Matlab to a block tool like Simulink and how you can use them efficiently. 2. Convert the designed prototype filter to highpass filter with cutoff frequency f_C=10,000 Hz.
Signal Definitions are A.H, B.L ,C.L, D.H and Z.L. It is recommended you apply DeMorgan's Theorem first to the above equation. Draw (on paper) a circuit diagram implementing Z, using the minimum number of gates.
