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.
Identify the bus types and the unknown variables of the power flow problem. Write the complete set of equations needed to solve the load flow problem.
Understanding low, high and band pass filters, A signal in the IF section of an FM radio receiver occupies the frequency band 10.61 MHz to 10.79 MHz. Compute the bandwidth of this signal.
Draw a labeled sketch of x(t) over a few periods: be careful, make sure you follow the exact definition of x(t)
What do the letters PCM and PAM stand for? Why is PCM transmission preferred over PAM transmission? Give at least two reasons in your answer.
An amplifier with a voltage gain of +30db, an input resistance of 8 k ohms, and an output resistance of 2 k ohms is used to drive a 2 k
Important information about Digital signal processing, (a) Design a lowpass FIR digital filter using "remez" routime in Matlab for the following specifications:
Ziegler-Nichols Open Loop Tuning Often, when working with a faster loop, many people will opt only for a PI control philosophy
The outputs of two "NAND" gates are connected to the inputs of an "Exclusive Or" gate. Each of the "NAND" gates has one input at a logic high level, and the other input at a logic low level. What is the output of the "Exclusive Or" gate?
A terrestrial radio link transmits a CDMA signal from a base station using a spreading code with a chip rate of 1.0 Mchips per seconds. The message data rate of the signal is 10 kbps.
