The normalized sinc function, the impulse response of a sinc-in-time filter and the frequency response of a sinc-in-frequency filter.The rectangular function, the frequency response of a sinc-in-time filter and the impulse response of a sinc-in-frequency filter.
In signal processing, a sinc filter can refer to either a sinc-in-time filter whose impulse response is a sinc function and whose frequency response is rectangular, or to a sinc-in-frequency filter whose impulse response is rectangular and whose frequency response is a sinc function. Calling them according to which domain the filter resembles a sinc avoids confusion. If the domain is unspecified, sinc-in-time is often assumed, or context hopefully can infer the correct domain.
