The loop gain of an amplifier is given by
The pole at fP1 = 104 is to be moved such that the feedback amplifier with a closed-loop low-frequency gain of 40 has a phase margin of 60 degrees.
(a) Find the value of β.
(b) Determine the new pole frequency.
Which of these metrics are dependent on link conditions: CINR, SNR, or BER Evaluate the pros and cons of using the SNR and signal - to - interference - noise ratio ( SINR ) for estimating signal quality versus using the absolute value of the signa..
Design a circuit which provides 20 dB of gain. The 3dB filter points should be 50 HZ and 50 KHZ. Use a bipolar power supply (+/- 9V). Your circuit should be able to provide a minimum of 5 Watts of output power.
Generate the run-length codes for AC coefficients.
A channel of bandwidth 4 kHz is available. Determine the data rate that can be accommodated for the following line codes (assume a bandwidth to the first spectral null)
A person has a problem with hum in a home stereo system and discovers that by disconnecting the ac power, green wire, ground to the amplifier the hum goes away. Why is this not an acceptable solution to the problem?
Draw a circuit diagram to model the functionality of the arithmetic circuit attached. You may draw the circuit on the levels of gates, multiplexers, adders etc.
At a certain radian frequency, ω, a 25 Ohm resistor in parallel with a capacitor, C, has the same impedance as a 20 Ohm resistor in serires with a 0.01 F capacitor. What are the values of ω and C.
How often should the controller be executed? Show just the equations (no software or hardware is required), calculating Duty as a function of Speed and Desired.
It is used in a quarter Wheatstone bridge with three other fixed 100 W resistors. If the strain gauge constant is 2.0, find the output voltage when the input voltage to the bridge is 10 Volts and the strain is 500 m strain.
Explain why the C0 and C1 probabilities of a PI may not be equal to 0.5. Give an example of a circuit or application where this could occur.
moore sequential circuit has one input and one output, that creates a pulse when ever its input signal goes from 1 to 0 after this pulse a new pulse will not be given unless the input signal is again returned to 1 and then tranistion back to 0.
Two equal resistors R connected in series across a voltage source V dissipate power P. What would be the power dissipated in the same resistors when they are connected in parallel across the same voltage source
