homework

Hi i am trying to make a 12hr clock in quartus using these two chips for a 7 segment display I cant figure out hour to get the hours as i have the minutes and seconds done aleady please help. This is what ive done so far

Could someone please help design a cascode amplifier with these parameters? Frequency range: 200 kHz to 20 MHz Input signal voltage: 10 mV to 1 V Power supply voltage: 5 V to 12 V Power consumption: up to 100 W And if possible, please also include the calculations showing how to achieve this...

Hello AAC, I have a laboratory requirement about making a circuit with the following characteristics: With good variety of components (Say, 12 unique components, but there is no specific number) With 741/358 and/or a 555 timer With 3 analog sensing elements (Say, a LDR) No microcontrollers No...

hello, sorry for my bad english I have two problems which i don't know how to solve and I would be really grateful if you could help me: 1. The maximum value of alternating current of 50 Hz frequency is 200√2 A. The time countdown starts from the zero value of the current in the increasing...

Hello everyone. I have a problem regarding low pass pi filters. For context, I am a physics student and this is way, and I mean WAY outside of my purview. So much so, that I can't find this circuit, or anything like it in my textbooks. After some gruesome research, I found some formulas which I...

Hello allaboutcircuits! The instructions for my task are above. There are no explicit restrictions, but I want to use flipflops for this one. We were taught no prior knowledge except basic gates and elementary logisim operation. I'm learning as I go and so far, an 11-state (0000-1010) up...

Is there any resistive humidity sensor that I can power with a dc voltage and with analog output not digital? I prefer araw sensor not a module.

Can someone please tell me how many registers are displayed, and what the sizes are in bits and words of the registers in the screenshot I provided.

Is the second pole in the node marked in red? I am not sure

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...

So i have this simple circuit.While my voltage input is 5V why is my output 3.3V? Can someone explain this to me.Thanks in advance!

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. > 1) A sensor...

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
