Method and an apparatus for sampling rate conversion

An apparatus for converting an input signal to an output signal wherein at least one of the input signal and the output signal is non-uniform, the apparatus comprising:

• a signal input,
• a signal output,
• a controller being configured to:
• receive the input signal from the input, the input signal representing, at each of a plurality of first points in time, tau, a value x(tau),
• generate the output signal representing, at each of a plurality of second points in time, t, a value y(t), y(t) being determined by multiplying:
• a first factor depending on the second points in time but not the first points in time with
• a sum of x(tau) multiplied by a second factor depending on the first points in time but not the second points in time and
• output the output signal from the output.

A computer program stored on a computer-readable medium for converting an input signal to an output signal wherein at least one of the input signal and the output signal is non-uniform, the computer program comprising executable instructions that cause a computer to:

• receive the input signal representing, at each of a plurality of first points in time, t, a value x(tau),
• generate the output signal, the output signal representing, at each of a plurality of second points in time, t, a value y(t) by multiplying:
• a first factor depending on the second points in time but not the first points in time with
• a sum of x(tau) multiplied by a second factor depending on the first points in time but not the second points in time, and
• output the output signal.
