Consider the parallel form flow graph shown in Figure P6.48
(a) Assume that the system is implemented with two's-complement fixed-point arithmetic, and that all products (multiplications by 1 do not introduce noise) are immediately rounded (before any additions are done). Insert round-off noise sources at appropriate locations in the flow graph to model the rounding error. Indicate the size (average power) of each noise source in terms of σ2B, the average power of one (B + 1)-bit rounding operation.
(b) If the products are rounded as described in part (a), the output can be represented as yˆ[n] = y[n] + f [n] where y[n] is the output owing to x[n] acting alone, and f [n] is the total output due to all the noise sources acting independently. Determine the power density spectrum of the output noise
Demonstrate that the peak critical heat flux occurs at approximately one-third the critical pressure (Pc = 221 bars). Since all common fluids have this characteristic, suggest what coordinates should be used to plot critical heat flux-pressure val..
Design a second-order band-pass filter for a system with sampling frequency of 18 kHz that is tuned for f=5kHZ The filter should not have any sample delay (the numerator and denominator orders are equal)
Determine the periods and find exponential fourier series coeffecients of functions. A.) f(t) = 2(cost)(cos2t) B.) g(t) = 3 + 2e^-j2t + 2e^j2t + 2cos4t C.) h(t) = 4
An InP TED is 0.5 pm long with a cross sectional area of 10" cm2 and is operated in the transit-time mode.(a) Find the minimum electron density no required for transit-time mode.
Assuming the current flowing through R2 is one-tenth of ID1, calculate the values of R1 and R2 so that ID1 = 0:5 mA.
Discuss why it is important to consider the Gain Bandwith Product (GBW) and the Slew Rate (SR) when selecting an op amp for a particular application. What other factors are important and why.
Describe the performance differences between an AM and FM system. Be sure toinclude parameters suchas: Power efficiency, spectral efficiency,noise immunity,and performance.
Two transistors have EBJ areas as follows: AE1 = AE1 = 400μm x 400μm and AE2 = 0.4μm x 0.2μm. If the two transistors are operated in the active mode and conduct equal collector currents
How to calculate power factor correction for my installation ? Please see the file attached to check the Questions . - Calculate Actual Load (kW) (Load) Power kW = Volts V x √3 x Current I x Power factor Pf
The messages being sent are 2 milliseconds long. Computer A starts sending a message on the bus; 250 microseconds later, Computer B starts to send a message, and 250 microseconds after that, Computer C starts to send a message.
If a RAM memory has a 5-to-32 row address decoder and a 6-to-64 column address decoder, and eight pins I/O, what is the size of the memory
A voltage of 60cos(4πt) V appears across the terminals of a 3mF capacitor. Calculate the current through the capacitor and the energy stored in it from t=0 to t=0.125 seconds.
