摘要：
A medical system having an endoscope probe intubated into a body, a signal processing circuit for processing a signal for the probe and an electric source circuit insulated from a commercial electric source. A part of the signal processing circuit connected to the probe is isolated by an isolation circuit to secure the safety. An impedance element is employed to prevent a malfunction by reducing an emission/permeation of noises. No adverse influence is thereby exerted on outside units.
