Can you ring LC tank with pulsed DC?

And at which harmonic?


You didnt answer at which harmonic?

Update 2:

If resonant frequency is 60KHz, should i just pulse it with 120KHz?

Update 3:

But at 60KHz every other dc pulse will oppose the ringing as it goes in opposite direction.

Update 4:

I guess the best would be periodic pulse in phase with ringing.

    Yes, a DC pulse will cause an LC circuit to ring. The length of the 'ring' is dependent on the loaded Q of the network.

    Following on from derfram, the best frequency would be 60kHz, not 120Hz because in the middle of the 60kHz the 120Hz pulse will oppose.
