ABSTRACT:
A sampling frequency converting apparatus converts an input digital television signal which is sampled at a first frequency into an output digital signal which is sampled at a second frequency. The apparatus comprises a memory, a write-address producer which operates in response to the first frequency, a read-address producer which operates in response to the second frequency, and an interpolation circuit. The speed of the converting operation is determined by the difference between the first and second frequencies.
