Design a circuit to multiply two 2-bit numbers - a,b and c,d and produce a 4-bit product -- w,x,y,z. Show a truth table and the equations.
A box contains 50 diodes of which 10 are known to be bad. If the first diode drawn from the box was good, what is the probability that a second diode drawn will be good
Use decomposition to find the minimum gate input cost, multiple level implementation for the functions given, using AND, OR, NOT, XOR gates: a) F(A,B,C,D)=sigma(m)(5,6,7,9,10,11) b) G(W,X,Y,Z)=sigma(m)(5,6,7,9,10,11,14,15)
Design a counter whose count sequence is all prime numbers greater than 4 less than 55. Provide the excitation equations for the FlipFlops.
A He-Xe mixture containing 0.75 mole fraction of helium is used for cooling of electronics in an avionics application. At a temperature of 300 K and atmospheric pressure, calculate the mass fraction of helium and the mass density.
A 50 kW load operates from a 60 Hz 10 kV rms line with a power factor of 60% lagging. Determine the capacitance that must be placed in parallel with the load to achieve a 90% lagging power factor.
a thermocouple is a heat-sensing device that typically outputs a signal in microvolts, such as 10 microvolts.if the signal transmitted to the controller needed to be 10 volts, what approximate amplification would the transmitter need to supply
When the beam is not broken, light from the transmitter hits the receiver and turns on the output transistor from the receiver. Their purpose is to detect objects as the objects break the beam. design a through-beam photoelectric sensor
A volume is divided into two equal parts by a partition. The left volume has N atoms. The atoms have a mass m. A hole of area A is made in the partition at time t=0 A)Develop an expression for the number of white atoms on each side of the partition..
The noise signal is measured to be 1.35 V. The output difference signal is 3.95 V and the common-mode output signal is0.95 mV. Determine the common-mode gain, the differential mode gain, the CMRR, and the CMR (in dB) for the amplifier.
A step-down transformer has a 120V rms primary voltage applied and a 12V rms voltage is measured at thesecondary. Assuming the transformer can be considered ideal,determine the turns ratio, n.
Draw a diagram for a MOD-10 Johnson counter using a 74HC164. Makesure that the counter will start the proper sequence when it isturned on. Determine the count sequence for this counter and draw the decoding circuit needed to decode each of the 10 ..
Suppose we have a 4Kword memory RAM with each word containing 32 bits. How many address bits and how many output bits are needed. Draw the block diagram of a negative edge-triggered JK FF which is asynchronously set by a 1 and asynchronously reset b..
