A friend proposes the following scheme for representing rational numbers (numbers that can be represented as p/q, where p and q are both integers and q = 0) using 13 bits. The leftmost 6 bits will be the signed binary integer p; the rightmost 7 bits will be the signed binary integer q.
a. What is the largest value representable using this scheme?
b. What is the smallest positive (non-zero) value representable using this scheme?
c. What's the smallest value (i.e., most negative) representable using this scheme?
d. Give a pair of distinct bit patterns that both represent the same non-zero value under this scheme.
e. Give an unusable bit pattern under this scheme (a pattern that does not represent a rational number).
f. Propose a change to the scheme that keeps it simple but increases the number of distinct values representable.
An ideal non-degenerate silicon step junction diode with an intrinsic level Ei exactly at mid band-gap is fabricated. Answer all questions related to this diode. a) If Vbi = 0.65V and NA=4ND, what is the doping concentration in the quasi neutral n ..
You deposit 10% of your annual salary at the each of each year in a retirement account. F= Future worth A1= first annual deposit n=number of years g=geometric gradient F=A1(1-(1+g)^n(1+i)^-n/(i-g))(1+i)^n use Matlab to graph the function.
If V = 12sin( 2 pi 1800 + 45). What would you read on a DMM Would this voltage be for an inductor or capacitor What would be the frequency and phase What does the 12 stand for Explain.
Given the DSP system, where the sampling rate of 4000 Hz is used, the anti-aliasing filter is the Butterworth filter with a cut-off frequency of 200 Hz, and the percentage of aliasing level at the cut- off frequency is required to be less than 10%
A universal shift register can shift in both the left-to-right andright-to-left directions, and it has parallel-load capability. Draw a circuit for such a shift register.
two magnetically coupled coils have self-inductances of 52mH and13mH, respectively. The mutual inductance between the coilsis 19.5mH. a. what is the coefficient of coupling b. for these two coils, what is the largest value M can have
A container having a volume of 0.2 m3 contains nitrogen at a pressure of 100 kPa and a temperature of 15°C. If 0.2 kg of nitrogen is pumped into this container, calculate the final pressure after the gas has returned to its initial temperature.
design a system that has an output of 1 when the input has been 0 for exactly 7 clock times first by using a 4 bit
