Basics of Pspice: Start the project; construct the circuit: use “Pspice” devices, picking and placing components; use appropriate signal sources for: transient analysis (time domain response), AC analysis (frequency response), DC analysis; selecting and placing markers; “simulate” the performance of the circuit: transient analysis (time domain response), AC analysis (frequency response), DC analysis, run the simulation, edit the “simulation profile”, save the project, recall and restart.
