Abstract
Provided is signal processing device including superconducting quantum interference device (SQUID) sensors configured to sense a signal for each of a plurality of channels, analog to digital converters (ADC) configured to convert analog signals input to a predetermined number of channels from the SQUID sensors into digital signals by using a clock signal, local oscillators corresponding to the ADCs, respectively and configured to generate the clock signal having a reference clock frequency for an operation of a corresponding ADC, and a controller configured to the local oscillators to enable the reference clock frequency to have a frequency beyond a frequency range available to the SQUID sensor.
