Abstract

A signal processing circuit has two types of filters: an IIR filterand an FIR filterhaving an equivalent transfer function at all times. In an adjustment mode in which the signal processing circuit is adjusted to have an arbitrary transfer function, the signal processing circuit makes a configuration setting to use the IIR filter. When completing the adjustment or in a signal processing mode, the signal processing circuit makes a configuration setting change to switch to the FIR filterhaving the equivalent transfer function.
