The basic amplifier in a feedback configuration has a low-frequency gain of A = 5000 and two pole frequencies at f3-dB1 = 10 Hz and f3-dB2 = 2 kHz.
The low-frequency closed-loop gain is Af = 100.
Determine the two 3 dB frequencies of the closed-loop system.
For the motor in Problem 6-5, what is the slip at the pullout torque? What is the pullout torque of this motor?
A landscaper tries to plumb a tree by applying a 240-N force as shown. (a) Replace that force with an equivalent force-couple system at C.
An Alternator is found to have its terminal voltage on load condition more than that on no load. What is the nature of the load connected
Design a full subtractor, that is a circuit which computes a-b-c, where c is a borrow from the next less significant bit. (Hint: Denote the difference as d, and a borrow from the next more significant bit as p, then develop a truth table for the p..
The objective is to design a discrete common-emitter amplifier, the common-emitter amplifier is to have the following specifications: single ended input and output Av approximately 20 in the midband 3-dB bandwidth extending from 10 Hz
Using the multimeter, measure and record the actual resistance values of the resistors. Set the DC power supply to provide 15V (verify with your multimeter), and build the circuit in Figure 1 on your breadboard.
Many communication systems connecting computers employ a technique known as "packet transmission." In this type of system, a collection of binary digits (perhaps 1000 of them) are grouped together and transmitted as a "packet."
(a) Determine the cone angle that will match the line to an infinite length biconical antenna. (b) For the cone angle of part (a), determine the two smallest cone lengths that will resonate the antenna.
Draw the individual and combined impedance (X pu) diagrams to a base of 10 MVA for the units and system - What would be the effect on the fault level of replacing the unit - Determine the pu impedance and the reactance of the interbus reactor for th..
Loop antennas are very common and are often used by amateur radio sites. In fact, the figure on the right is provided as an example what one may find when searching for loop antennas on the web.
The residential sector of PA consumed about 150.6x1012 Btu of electricity (www.eia.doe.gov). Assuming all of this energy comes from bituminous coal with a heating value of 14,000 Btu/lb. How MUCH coal did we burn?
A voltage source V(t)=100cos(6Π109t - 45(degrees))(V) is connected to a series RLC circuit. If R = 10MΩ, C = 100pF, and L = 1H, use phasor notation to find the following: a.) i(t) b.) Vc(t) (voltage across capacitor)
