I am trying to simulate LC circuit using external source that generates square wave of 503Hz of amplitude 2V as below:
Natural frequency of circuit above is 503Hz.So it must pass this much frequency.When I run the simulation of above circuit,capacitor gets damaged or shorted (don't know exactly) and it appears in circuit like :
and output becomes zero in oscilloscope.
But when I pass square wave of frequency 5kHz,sinusoid output is obtained.(as shown in image below)
Please guide me why such outputs are observed ? If it acts as band-pass filter,then it should pass simply frequency around natural frequency and same output as input i.e square wave should be observed.At higher frequencies (5kHz),output should simply be zero but why sinusoid ?
- I read from wikipedia that series LC circuit acts as band-pass filter having zero impedence at natural frequency.
- I am using Multisim 11.
