<p>The filter (DF) includes an input terminal (BE), which receives a signal (SE), and two parallel processing branches (VT1,VT2). Each branch includes a mixer (MA1,MA2) followed by a low-pass filter (F1,F2) connected to a second mixer (MV1,MV2). Each mixer receives a mixing signal (SM1,SM2) and generates a transposed signal (STFT1,STFT2) applied to the inputs of a subtractor (STR). The subtractor output is delivered to the filter output (BS).</p> |
