Logic Circuit

19. The outputs of two "NAND" gates are connected to the inputs of an "EXCLUSIVE OR" gate. Each of the "NAND" gates has one input at logic high level, and the other input at a logic low level. What is the output of the "EXCLUSIVE OR" gate? a) logic high b) logic low c) logic low, unless the output is "open collector" d) n ...continues

Electric Heater

The Problem: An Electric Heater is connected to a constant 250-V source and absorbs 1000 W. Subsequently, this heater is connected to a constant 210 V source. What power does it absorb from the 210-V source? What is the resistance of the heater? My Answer: Using Hint from problem 2.5-7: Model the electrical heater as a resis ...continues

Determine the voltage drop (from top to bottom) across the 16 ohm resistor the circuit shown.

Referring to the attached document: Determine the voltage drop (from top to bottom) across the 16 ohm resistor the circuit shown. My Answer: 16Ohm/(16Ohm+8Ohm)*12V=8V Additionally: Referring to the circuit shown, determing the voltage drop across the 4 ohm resistor: My Answer: 4Ohms/(4Ohms+8Ohms)*12V=4/12*12V=4V ...continues

Thevenin Equivalent Voltage

Please refer to the diagram attached. A resistor, R, was connected to a circuit box as shown. The voltage, v, was measured. The resistor was changed, and the voltage was measured again. The results are shown in the table. Determine the Thevenin equivalent voltage vt of the circuit within the box. My Answer: Rc=Vt/it I=6V/( ...continues

interpreting a step signal.

The image is described by y(t)=t-tu(t-1)-t(u(t-2))+t(u(t-3)). I don't get this. please point out where the signal turns on and off and why. To me, it looks like a ramp, a step, and then a ramp with neg amplitude. I can do the rest of the problem, i.e. the laplace transform and the other parts. Thanks.

Circuit Analysis

Consider the given circuit; the voltage step is an "ideal" pulse going from 0V to 4V and then back to 0V; the pulse width is 5 microseconds wide. How do I find the voltage across the resistor, Vr(t) 7 microseconds after the rising edge of the input impulse?
