Given that 7483 is a 4-bit parallel adder chip, how do you build a 16-bit parallel adder circuits? Which factor limits the propagation delay of ripple counter? How is a J-K fl ip-fl op made to toggle?
A three-stage amplifier is shown. The operating bandwidth is 500 KHz at a temperature od 25 degrees C. The output load is 1000 ohms. calculate the total NF as a number, calculate the output noise power, and calculate the output noise voltage.
plug the following items into a single circuit breaker in your house (120 V): 0.3 hp fish tank pump, a 9000 watt space heater, a 1800 watt hair dryer, a TV using 409 watts. Calculate the minimum rating of the circuit breaker necessary to safely ca..
What would you consider to be evidence of tit-for-tat pricing? How can you distinguish tit-for-tat pricing designed to sustain "collusive" pricing from competitive pricing?
A lighting load operates from a 208-V 60-Hz supply and is rated 1.0 kW with a power factor of 0.9 lagging. A 40-µF capacitor is connected in parallel with this load. Calculate the total power factor and the percent change in line current.
The following currents are measured in the same direction in a three-branch parallel circuit: 250 mA, 300 mA, and 800 mA. What is the value of the current into the junction of these three branches?
The voltage across the load must remain between 4.7 and 5.0 V for all values of load current. Come up with (draw) a voltage-divider network to supply the load. You may assume that resistors of any value desired are available.
Assume that a parity-bit is transmitted for every nibble of data. Design a logic circuit that checks the nibble of data and transmits the proper parity bit for both even- and odd-parity systems.
Assume the resistance of a human person was 500 ohms, if a person was struck by lightning with a peak voltage of 100,000 volts, what was the peak current that would flow through the person
There are contacts at the two ends, x=0,W. The contact at x=0 is transparent. Light falls on the contact at x=0 creating electron-hole pairs at a rate GL(x)=GL,0 exp(-x/λ), λ =/= L0. Calculate the steady-state excess electron concentration.
Tones Input In To An Amplifier, Suppose two tones are input in to an amplifier. The tones are pure sinusoids with one at frequencies 8GHz and the other at frequency 8.03GHz,(delta f =0.03GHz).
A 75-W, 120-V tungsten incandescent lamp has a resistance of 19.2Ω when no current flows through it. 1.What is the resistance of the lamp when it is connencted to 120-V cource
