Briefly describe how we can use a decoder optimally to implement a given Boolean function? Illustrate your answer with the help of an example. 6. Draw truth tables for the following:
(a) an 8-to-1 multiplexer with active LOW inputs and an active LOW ENABLE input;
(b) a four-line to 16-line decoder with active HIGH inputs and active LOW outputs and an active LOW ENABLE input;
(c) an eight-line to three-line priority encoder with active LOW inputs and outputs and an active LOW ENABLE input.
An aperiodic signal x(t) = 2sinc(2t) is multiplied by a periodic rectangular pulse train s(t) with fundamental frequency F0 = 4 Hz and the fundamental rectangular pulse given by p(t) = 1, 1/80 t 1/80 0, otherwise to obtain a signal xs(t) = x(t..
The input analog signal is bandlimited to 3900 Hz. The overall frequency response is required to satisfy the following: Gain > -1.33 dB for frequencies less than 1, 333.33 Hz Gain
Charge is distributed uniformally along a straight wire. the electric field 2 cm from the wire is 20N/C. The electric field 4cm from the wire is:
A capacity coupled amplifier has a midband gain of 1000 V/V, a single high-frequency pole at 10 kHz, and a single low-frequency pole at 100 Hz. Negative feedback is employed so that the midband gain is reduced to 10.
Define line impedance. What is its value for an infinitely long line?
In a single-phase rectifier the input current can be approximated to have a triangular waveform every half cycle with a peak of 10A and a base of 60. Calculate the rms current through each diode.
Design a two-levelcombinational logic circuit to implement theadditionof two 2-bit numbers. Donot use half adders or full adders as building blocks forthis circuit. Rather, follow the logic circuit design process discussed in class.
Write the 9S12DP256 assembly language instructions below a programmer could use to copy the 3rd variable from a 10-byte array into Accumulator B.
Repeat (a), but this time hold the slot width to 0.5?x and vary the slot length from ?y to 10?y. How does the transmitted amplitude vary with the slot length?
If there are 500 atoms in the sample and assuming that from any state all possible downward transitions are equally probably, what is the total number of photons that will be emitted when all atoms return to the ground state
Calculate the built-in voltage of a junction in which the p and n regions are doped equally with 10^16 atoms/cm3. Assume ni =.5x10^10/cm^3. With the terminals left open, what is the width of the depletion region
