Derive a scheme for performing subtraction using BCD operands. Show a block diagram for the subtractor circuit.Hint: Subtraction can be performed easily if the operands arein the 10's complement (radix complement) representation. Inthis representation,the sign digit is 0 for a positive number and 9for a negative number.
For a system, we learn the following three properties: (1) Memoryless, (2) Time-variant, (3) Linear, and (4) Casual. Determine which of these properties hold and which do not hold for each of the following continuous-time systems.
Suppose A and B are 3-bit signed-magnitude numbers and A =(A2, A1, A0) and B = (B2, B1, B0). a) Write a logic expression for G, which is true when and only when A > B. b) Write a logic expression for GE, which is true when and only when A ≥ B.
Explain what the cumulative probability distribution function indicates in this case. If the rms value is given by 2 sigma, compute the percentage of time that a signal is 12 dB or more below the rms value for a Rayleigh fading signal.
how many roots of the following two polynomials are in the right half plane and left half plane P(s)= s^5 + 3s^4 + 5s^3 + 4s^2 + s + 3 P(s)= 3s^7 + 9s^6 + 6s^5 + 4s^4 +7s^3+ 8s^2+2s+6
Determine the number of gates needed to implement an eight-bit carry-lookahead adder assuming that the maximum fan-in for the gates is four.
A CB amplifier is operating with R load = 10 kiloohms, Rc = 10 kiloohms, and R signal = 100 ohms. At what current Ic should the transistor be biased for the input resistance Rin to equal that of the signal source
After absorbing a photon in excess of its bandgap energy, the photo excited electron in the conduction band (CB) of a semiconductor moves spontaneously to the interface between the semiconductor and the liquid electrolyte.
A dc power distribution cable has two #6 copper wires. The copper wire table in the textbook lists each wire as having resistance of Ro=.4028 ohms per thousand feet at temperature of 25C. The temperature coefficient of copper is alpha=.004 per C.
steam is condensed on the outside of a heated exchanger tube by pressing air through the inside of the tube. the air enters at 1.2 bars, 20 degree c and a speed of 10 m/s. the air exits at 80 degree c. the steam enters 3 bars, 200 degree c
Calculate The Average voltage generated in 6 turn full pitch coil of a 25 cycle alternator if the flux per pole is 7.2 x 10^5 maxwells. What is the effective voltage if the waveform is sinusoidal.
The value of Q is 1 if and only if the number of 1's in the sequence of input P is not divisible by 2 and not divisible by 3. Otherwise, the output value Q is 0. Draw a state transition diagram for the state machine using as few states as possible..
