find the transfer functions, seros, and poles for the following systems:a. (D^2+10D+24)y(t)=(5D+3)f(t)b. (D^2+4D)y(t)=(3D+2)f(t)
"Power Outage" refers to that the receive signal power falls below a certain threshold. Consider for a RF signal in a Rayleigh fading channel with average receive signal power 22 = - 80dBm. What will be the power outage probability of this channel..
A bank of induction motors cosumes 36kW at 0.78pf lagging from a 60 Hz 240V RMS line. If 200μF of capacitors are placed in parallel with the load, what is the new power factor of the total load
Calculate the total capacitance of the structure that consists of a dielectric inserted between two conductive parallel plates that are separated by adistance 3d. The dielectric of thickness d is inserted in the center of the structure.
If we wish to design a communication system which carries voice securely, we need to ensure that others cannot tap into the conversation. In digital transmissions, we can do this by encryption.
A system is needed to measure flow, which continuously cycles between 20 and 30 gal/min with a period of 30 sec. The required output is a voltage varying from -2.5 to +2.5 V for the cycling flow range. The sensor to be used has a transfer function..
a 14-bit successive approximation adc is used to sample a signal that has a full-scale range of 8V and a clock frequency of 12 MHz and a jitter of 50ns.initially this is used without a sample and hold amplifier.
consider the circuit of fig. 5.59 for the case vcc vee 10v i 1ma rb 8komega and beta 100. find all dc currents
Suppose you go to a consultation meeting with a potential client.The client requires a single beam antenna with HPBW's of theta1 = 15 degrees in one plane and theta2 = 30 degrees in the other plane. During the meeting, the potential client men..
1. How would you bias a BJT in a common emitter amplifier in order to minimize the Miller feedback capacitance 2. Explain how it is possible to identify the different current transport mechanisms.
Suppose that a voice signal normally occupies 30 kHz of bandwidth and has a signal-to-noise ratio of 20 dB. Spread-spectrum techniques are used to increase its bandwidth to 2 MHz. (a) What is the signal-to-noise ratio of the spread signal
Although this forms PNP and NPN transistors, the bias of the regions is designed so the junctions are reverse biased and the electric field effects on the channel are supposed to control the MOS-FET transistor soperations.
build a solar power system that is used for aresidential application and demonstrate in front of my class. Here are the components used in this system: Solar panel,solar charge controller, 12 V lead acid battery, DC to AC inverter,and a battery te..
