Patent ID: 6940539

Claim:
An X-ray imaging system comprising: a. a video imager, b. a cable including: (1) a first end receiving a cable input signal from the video imager, and (2) a second end delivering a cable output signal, the cable output signal being different from the cable input signal; c. a cable length compensator including: (1) a first end receiving the cable output signal from the cable, (2) a first path leading from the first end, the first path including a variable resistance; (4) a second path leading from the first end, the second path including: (A) a first variable resistance, and (B) a parallel array of at least two capacitances; (4) an output amplifier into which the outputs of the first and second paths are summed; and (5) a second end extending from the output amplifier and delivering a compensator output signal, the compensator output signal being substantially similar to the cable input signal.
