Alternating indicator tasks?
Hello I need help with these two alternating indicator tasks I don't understand
Is a decoupling capacitor necessary here?
Good day, I'm currently designing a circuit board (powered by 5V), and I've heard several times that you should use a decoupling capacitor in front of various electrical components. Does a decoupling capacitor need to be placed in front of the following components? 1x RGB LED 1x ATtiny85 1x passive buzzer 1x DHT11 Is it…
Binary 0 – 1 calculation?
0 represented in binary = 0000 1 represented in binary = 0001 0 – 1 binary From 1 two's complement form 0001 = 1110 LSB + 1 = 1111 = -1 Decimal 0000 +1111 = 1111 = -1 Should fit! When you convert 0 – 1 in binary, you get 1 with a carry of…
How can I implement a random switching?
I'm building a model with several small diffusers that are supposed to represent fountains from geysers, but I don't want them all to run at the same time. Is there a controller or something similar with which I can run the diffusers randomly one after the other?
Determine switching function?
a) is clear b) s1 = nega s2 = neg b Now determine the switching function: y = a*s2 + s1 * b s1 and s2 inserted gives y = a * negb + nega * b Would that be correct? Why does it say "don't forget to invert afterwards" at the end of the…
Hazardous error in circuit?
Here you can see the signal propagation times of the circuit. h3 = b*negc Why does this short-term signal change from 0 to 1 occur here at h3 (hazardous error). I can see from the signal times above that c changes from 1 to 0 and, at the same time, b also changes from 1…
Specify the switching function of a circuit?
f moves to 1 for Which is correct here , nega*negb + c or nega*negb + negc ?
Draw a circuit (logic gate)?
I have in my exercise book 3 I've been given circuits and don't understand how they came up with the solution. I'm actually pretty clear about circuit 1, but I have no idea how they arrived at the solution for circuits 2 and 3. I already know the individual circuits like AND, OR, etc. Task…
BCD adder?
How do I get ü = ü4 + s1*s3 + s2*s3?
Bistable flip-flop?
What was written in pencil were just notes that had nothing to do with the circuit underneath My son's homework – unfortunately there are mistakes hidden somewhere Maybe someone can help
Full adder: after how many ns is the sum and carry reliably present at the output?
Each gate delays by 1NS c) After what time is the sum and carry reliably available at the output of the given VA if each gate is delayed by 1ns? To calculate the sum, I need Cout, which is entered as Cin in the calculation. I would say If each gate delays by 1ns, I…
Power supply for tube amplifier, isn't something missing here?
Hello everyone, The image below shows a power supply for a tube amplifier. It is a push-pull AB amplifier with ultralinear operation. Does this work as shown? I'm a bit skeptical. Isn't there a filter resistor missing between the electrolytic capacitors? (Marked with red arrow and question mark)
