A method is provided for analyzing the channel impulse response of a
transmission channel using a time-discrete adaptive equalizer connected
in series to the transmission channel, which it equalizes. The method
includes determining the IIR filter coefficients (a.sub.n) of a recursive
filter portion and the FIR filter coefficients (b.sub.n) of a
non-recursive filter portion of the time-discrete adaptive equalizer, at
least partially allocating the IIR filter coefficients (a.sub.n) and the
FIR filter coefficients (b.sub.n) to input vectors for a discrete Fourier
transformation, determining output vectors from the input vectors using a
discrete Fourier transformation, forming discrete transmission function
values by division of the output vectors, and determining the channel
impulse response from the channel transmission function using an inverse
discrete Fourier transformation.
