1. The problem statement, all variables and given/known data Hi in response to my previous thread (principles behind the waveform selector circuit), I would now like to run a SPICE simulation using the PSPICE schematics software to obtain the theoretical values before entering my lab session. I have uploaded the schematic for your reference. 2. Relevant equations Right now I have constructed the circuit in the program but I am unsure of which switch, transistor (BC548) and input signal to put in. Also if I want a square wave input, which settings do I need to configure? Assuming then the circuit is constructed perfectly, how am I going to observe the output at the switch? 3. The attempt at a solution Kindly see attached for the circuit which I have constructed in PSPICE. I have left out the switch and the transistor. For the input signal I used a VSRC 5V power supply.
