Abstract: A digital adjusting signal for adjusting a multi-channel SQUID system is transmitted only to a control circuit module including a SQUID channel selected in an embodiment of the present invention and not transmitted to other modules. Accordingly, the digital adjusting signal is prevented from flowing into all SQUID adjusting channels to minimize noise generated by the digital adjusting circuit of the SQUID channel and to stably control the SQUID sensor without malfunction.

Abstract: Provided are an apparatus and a method for canceling magnetic fields. The apparatus includes a magnetic field canceling coil disposed adjacent to an inner wall of a magnetic shield room to surround the entire inner space or a portion of an inner space of the magnetic shield room; and a magnetic field canceling coil driver to supply current to the magnetic field canceling coil. The magnetic field canceling coil cancels a prepolarization magnetic field established on the wall of the magnetic shield room by a prepolarization coil disposed in the center of the magnetic shield room to minimize magnetic interference caused by the magnetic shield room.

Abstract: Provided are a signal processing apparatus and a signal processing method. The signal processing method include receiving a serial signal including an information frame including channel information and data information of a corresponding channel, extracting a clock signal from the serial signal, generating a load signal when a clock count reaches a maximum clock count by calculating the clock signal; converting the serial signal to a parallel signal according to the load signal, and changing the maximum clock count by comparing parallel-converted parallel channel information with a load count indicating the number of local signals.
