horizontal output transformer การใช้

• Otherwise, some sort of relaxation oscillator would be useful so you can have repetitive events . ( In some old'scopes, the horizontal trace signal was externally available and could be used ! ) Given an impulse, I guess you could evaluate the self-resonant frequency based on provoking ringing of the inductor; we used to test " flyback " transformers ( television Horizontal output transformers ) in that way.
