I have just been thinking what i can do, I have thought that maybe having Vin and next to Vin connecting a pn junction diode so that any point before the turn on voltage, Vout would equal 0. (trying to get the idea from the half wave rectifier.)
but don't know how to get the 3.6 value as my...
It says using diodes, resistors, and zener diodes only, design a circuit whose output remains zero for vin<3.6V, but equals vin minus a drop of 3.6V for vin>3.6V. and the circuit has to work when the input voltages are below 0 as well as above 0. and help is appreciated.
If you have a phasor that has a negative magnitude (ie -3<38degrees) what is the best presentation. I believed it was just erasing the - sign and adding or subtracting 180degrees. Correct me if wrong
