A CB amplifier is operating with Rl = 10 kohm, Rc = 10 kohm, and Rsig = 100 ohm. At what current Ic should the transistor be biased for the input resistance Rin to equal that of the signal source? What is the resulting overall voltage gain? Assume a = 1.
A machinable grade of aluminum is to be milled on an NC machine with a 20 mm diameter four tooth end miling cutter, Cutting speed = 120 m/min and feed = 0.008 mm/tooth. Convert these values to rev/min and mm/rev.
a defibrillator supplies a maximum energy dosage of 20 jouls, and the maximum voltage of 8 volt. suppose it is desired to charge the capacitor from an ideal DC current source, and they want to do it in less than 80 seconds.
Plot the signal x(n) 0
The speech quality for a particular mobile communication system is just acceptable when the received power at the terminals of the mobile receiver is -104 dBm. Find the maximum acceptable propagation loss for the system, given that the transmit po..
What is the bandwidth occupied by this signal, and the noise bandwidth of the receiver for this signal? Find the BER at the receiver output and the average time between errors.
Given the characteristic equation: F(z) = z^3 + z^2 + kz - 0.5 = 0 a) Use the Jury test to determine the range of "k" that ensures the system is BIBO stable. Show any inequality graphs and how they are combined to determine the valid range of k.
Based on these equations, determine the maximum power point. This is the value of and T that result in maximum power. State the power and the (,T) values. Do not assume this happens at 0.5T. The best way to do this is to make an Excel spreadsheet.
Write Truth Table of a Half Adder with inputs A and B and output Sum and carry. How many 2-input NAND gates are required to realize this function. If a ROM is used to realize this function what is the size of ROM
In a MOS cascode amplifier, the cascode transistor is required to raise the output resistance by a factor of 40. If the transistor is operated at Vov = 0.2 V, what must its Va be
What is the average power in Watts needed of a machine that cools 10 lb/minute of dry air from 20 to 15 degrees Celsius
a. Describe the operation of a typical NMOSFET transistor used both as an amplifier and a switch. b. List the 3 regions of operation and draw the I-V characteristic curve. c. Show the effect of channel length modulation on your graph.
Design a common-emitter BJT amplifier with a gain of -100 (well above 3dB point) and a 3dB point at 100Hz. Assume beta = 100, Ic (quiescent) = 1mA, Vcc=20V. You can omit the output capacitor, but should bypass your emitter resistor.
