i have done a simulation on Bandpass filter. but when i do AC analysis i will get a straight line of input signal. how can i get continuous cycles of input signal. thankyou.
You will be giving a wide range of frequencies, and you will be select AC as transient analysis.
Hence it shows Amplitude as a single line that is maintained across these frequency ranges.
I hope you understood the difference between AC analysis and Transient Analysis.
