Hello everyone, I'm new here.
So I've got this assignment that asks me to use JK flip-flops in order to create a circuit that obeys the following truth-table:
The thing is, I have no idea on how to get these results at all. From what I understand, first two lines imply that PRE and CLR are both...
Hello,
in the following image you can see a circuit with a npn transistor. I marked the given values with red and the unknown with blue. Below the circuit you can see my calculations and solutions. I'm stuck at finding I1. I would be very thankful for some guidance.
Hi! thanks in advance for the help.
I'm trying to solve this exercice for school but a really can't seem to get it right.
I get really confused when that VDD apperas and can't identify the feedback mesh
Here is what i think it is:
But then again i'm not sure if that vdd or that resistor...
Can you tell me if my result results are correct, and if there are errors where are they?
I used the symbol rms to indicate the root-mean-square, Avo is open-circuit voltage gain, Ap is the power gain, Rl is the load resistance. i stands for input, s for source and o per output.

I am trying to solve a numerical where the Speed of a DC motor operating at 15V was measured to be 2000 rad/sec. Now a PWM signal is applied to the same motor to get a speed of 400 rad/sec. If the voltage amplitude of the PWM signal is 5V, then what should be the value of duty cycle?
I know the...
1) Enter your expression for the dc component of the output voltage V:
2) For the buck with input filter, enter your expression for the dc component of the L2 inductor current I2:
3)For the buck with input filter, enter your expression for the dc component of the capacitor C1 voltage VC1...
For Question 2.1, is the power 500W or 100W ? Do we need to apply the passive sign convention rule for power in whatever cases? Also, i’ve Learnt that we can check answers by balancing power in a circuit. But the power in this kind of circuits don’t balance out, but it is still valid. So when...
Okay so I have a project due tomorrow and I can't get it right, I need to find how many Ohms is the resistor Rb, the link is a screenshot to the task UBX is Uin. https://prnt.sc/t92gbh
Hello i have a question about a RC circuit. Can i represent with Laplace Transform the discharging of RC curcuit and how i get the transfer funtion to represent the free responce of the system
Here's the question : "For the two port network given, obtain the Z-parameters, ABCD (transmission) parameters and h (hybrid) parameters. What should be the value of load resistance connected at Port-2 for maximum power transfer when a voltage source of 25V is connected at Port-1." (Picture...
Good day!
I am currently writing a short report on DC machines and I intended to use the generator onboard the Bombardier/DHC Dash 8 Q400's Auxiliary Power Unit as a focal topic. Upon searching through several documentation (both from Bombardier themselves and some airlines like AirBaltic) I...
I have a problem in my ET212 class that I truly have no idea on where to start, I have the circuit design, but am clueless when it comes to the values that I need to use. I am not asking for answers, mainly just guidance on where I am supposed to start, or the steps i need to do to find my...
Hello. This may be a simple problem, but I'm struggling to obtain the resistance R found in the figure below.
First what's throwing my are the two voltage sources. I'm used to seeing these present in op-amps, but the way they intersect is throwing me. I'm not sure how to determine their...
Hello,
I got a homework exercise about the calculation of the power factor in a RL-circuit and in a RLC-circuit.
The question consists of 3 sub questions, I have managed to calculate the first 2 however I am struggling with the third one.
For the calculation of the third question, the other 2...
