A negative feedback amplifier has a close-loop gain Af=100 and an open-loop gain A=105. What is the feedback factor ?? If a manufacturing error results in a reduction of A to 103, what close-loop gain results? What is the percentage change of Af corresponding to this factor of 100 reduction of A?
A full adder is a circuit which adds three bits X, Y, Z together and returns two bits C and S to represent the total as a 2-bit binary number C S. C is the MSB and S is the LSB. For example, if X=1, Y=1, Z=0, the total should be 2, or 102 in binar..
The RS-232 serial port on a personal computer is transmitting 2400-bit/sec data using a polar NRZ line code that has a peak value of 12 V. Assume that binary 1's and 0's are equally likely to occur.
The intensity of solar radiation is 1366.1 W/m2 in space. This light strikes a 10 m2 solar panel of a satellite. Assuming that all the light is absorbed, how much force (momentum per second) is transferred
An infinite grounded conducting tube of radius 10cm is centered on the z axis. A concentric charged tube of radius 6 cm has a surface charge density of 24 uC/m2. A 1m long section of the charged tube is compressed to change its radius to 3 cm.
Implementation your algorithm using VHDL under Quartus. You are free to select the structural hierarchy of the implementation; the implementation could be behavioral, structural, or a mixed implementation. which the linear interpolation is to be e..
BJT Circuit Configurations Compare the input and output impedance for each configuration. Compare the voltage gain and current gain for each configuration.
A painter is standing on a work platform that is 27 feet above ground level. For fall protection, the worker's safety harness D-ring is attached to a 12-foot shock absorbing lanyard that is securely fastened to the structure at a point 40 feet abo..
When unmodulated the carrier voltage is 75 volts peak. An information (modulating) signal of 15 KHZ with 5 volts peak amplitude causes a frequency deviation of 22.5 KHz. If the load resistor RL= 100 Ohms, determine the following Modulation index
Suppose we have a causal LTI system with rational system function H(s). We don't know H(s), but we do have the following information: i. When the input to the system is x(t) = u(t), the output y(t) is absolutely integrable.
Assume that h is a random variable with PDF. Pn(h)=0.1*d(h-1)+0.9d(h-3). n is a zero mean white gaussian noise with variance 0.5. Assume that the channel state info is available at the reciever for each of the three branches.
