Assume that a in the flow graphs shown in Figure P6.47 is a real number and 0
(a) Assume that the two systems are implemented with two's-complement fixed-point arithmetic, and that in both cases all products are immediately rounded (before any additions are done). Insert round-off noise sources at appropriate locations in both flow graphs to model the rounding error (multiplications by unity do not introduce noise). Assume that each of the noise sources inserted has average power equal to
(b) If the products are rounded as described in part (a), the outputs of the two systems will differ; i.e., the output of the first system will be y1[n] = y[n] + f1[n] and the output of the second system will be y2[n] = y[n] + f2[n], where y[n] is the output owing to x[n] acting alone, and f1[n] and f2[n] are the outputs owing to the noise sources. Determine the power density spectrum of the output noise f1f1 (ejω). Also determine the total noise power of the output of flow graph #1; i.e., determine
(c) Without actually computing the output noise power for flow graph #2, you should be able to determine which system has the largest total noise power at the output. Give a brief explanation of your answer.
A sequential circuit receives decimal numbers encoded in BCD one digit (4 bits) at a time, starting with the least significant digit. The circuit outputs are the 10's complement of the input number, also encoded in BCD least significant digit firs..
The objective of the project is to design a grid-connected photovoltaic system in the Atlanta area. The system is to be installed with fixed tilt and azimuth modules
The donor ground states for tellurium in GaAs are 5.9 meV below conduction band (there are 2 of them because of spin). Atroom temperature (300 K), what is probability that a given ground state is occupied if the Fermi level (Ef) is 0.1 eV below Ec
Find the phasors for the current and for the voltages of the circuit shown in Figure. Construct a phasor diagram showing Vs, I, VR, and VL. What is the phase relationship between Vs and I?
A Si PIN photodiode has an i-Si layer of width 20 µm. The p+ layer on the illumination side is very thin (0.1µm). The PIN is reverse biased by a voltage of 100 V and then illuminated with a very short optical pulse of wavelength 900 nm.
The output is 1 when the pattern abca has occurred an even number of times in x(0,t). Give a state description of the system. Use a state vector approach and a minimum-number-of-states approach.
A signal x(t) is sampled 4 times and the samples are {x[0], x[1], x[2], x[3]}. Its DFT harmonic function is {X[0], X[1], X[2], X[3]}. X[3] can be written as X[3] = a x[0] + b x[1] + c x[2] + d x[3]. What are the values of a,b,c and d
Any causal signal x(t) having a Laplace transform with poles in the open-left s-plane (i.e., not including the j axis) has, as we saw before, a region of convergence that includes the j axis, and as such its Fourier transform can be found from its..
Construct a block diagram and an ASMD chart for digital system that counts the number of people in a room. The one door through whichpeople enter the room has photocell that changes a signal x from 1to 0 when the light is interrupted.
