Abstract
A filter apparatus has a first filter and a second filter. The first filter receives at least an up signal of a non-linear signal of which a single cycle is a predetermined period that includes an up interval and a down interval. In the up interval, a signal level non-linearly rises along a time axis. In the down interval, the signal level non-linearly falls along the time axis. The up signal is a signal in the up interval of the non-linear signal. The first filter performs linearization of the received up signal by improving linearity of the received up signal. The second filter receives at least a down signal of the non-linear signal. The down signal is a signal in the down interval of the non-linear signal. The second filter performs linearization of the received down signal by improving linearity of the received down signal.
