Abstract
A signal transmission circuit including a signal line through which the signal is transmitted from a signal source element to a signal receiving element, a grounding line arranged along the length of the signal line, and a high impedance element connected between the grounding line and the ground.
Claims8
A signal transmission circuit between a signal source element and a signal receiving element for transmitting a signal therethrough, comprising:
- a signal line through which the signal is transmitted from the signal source element to the signal receiving element;
- a grounding line arranged lengthwise along said signal line and consisting of solely one connection thereto at a predetermined position between an input end and an opposing output end, wherein said grounding line prevents disturbing effects of noises outside of a frequency range of the signal from being transmitted;
- and
- a resonant circuit connected solely from ground to said grounding line at solely the one predetermined position on said grounding line, said resonant circuit having a high impedance sufficient to cause a high speed transmission of the signal in the frequency range of the signal.
