Hello everyone,
I have a problem and I thought I should post it here because I can't quite get the hang of it.
I was tasked to make a circuit that is made of only NOR-gates. Seemed simple at first but then the restrictions came in.
The circuit needs to be made out of 4 NOR gates with 2 inputs...
the activity primary objtives are:
1. Make a half wave rectifier
2. Check the behavior of the diodes
3. assemble the circuit in the figure
4. Compare the waves over the diode and over the resistor
5. Add the capacitor and observe the waveform at the output of the circuit
6. Draw the waveforms as...
Hi all, I'm a math and physics major in my junior year. I am in a class called Scientific Instrumentation. The class requires that, by the end of the year, I must design and build a project on a breadboard. I decided that I wanted to build a breadboard that will play the melody of "Africa" by...
Hi all i have a problem with a LM741 op-amp,
when calculating the output voltage i should have when inputting 12vpp using the formula Vo = Vi(1+Rf/Ri) and the values being vi = 12 rf = 6k Ri = 1.5k i should be having an output of 60v, but when building and simulating my design i only have...
Question:
Design a 3-input NOR gate. If the PMOS devices are half as conductive as the NMOS devices determine the correct transistor sizes.
I understand how to design the pull up pull down circuit, just unsure about calculating the correct transistor sizes. Thanks
Good morning,
My 7yr old son came up with a concept for a science fair for a Wipe Reminder to remind kids to wipe when they get off the toilet. I've done some research and came up with an idea for a push or pressure switch as well as a digital recording module. My question is do I need some...
