Iam new in the forum. So hello everyone ! Also if this is not the place to send this message please forgive me..
I am new in electronics. And I want to learn if it is possible to compare two voltages and if they are equal then produce an output if not equal do not produce an output. Comparator produces output in terms of which input voltage is higher and than produce the result depending on that. But what i want to do is if they are equal then get an output voltage. Is this possible and if so how? Iam only allowed to use opamps resistors diodes capacitors etc.. basic elements... Thanks in advance
