Abstract
Disclosed herein is a signal processing apparatus including: a voltage-controlled oscillation block having a parameter high in correlation with a filter; a measuring block configured to measure an oscillation frequency of the voltage-controlled oscillation block; and a control block configured to control the parameter of the filter by use of a measuring result of the oscillation frequency obtained by the measuring block.
