<p>An analog filter for realizing the secondary transfer function by using an amplifier having a feedback loop. The filter has a first integrating function block (13) which integrates an input signal, second and third integrating function blocks (12, 14) which integrate an output signal, a first signal combining circuit (1) which combines signals from the first and second integrating function blocks (13, 12) with the input signal, a fourth integrating function block (11) which integrates signals from the first signal combining circuit (13) and a second signal combining circuit (2) which combines signals from the third and fourth integrating function blocks (14, 11) with the input signal and derives an output signal. <IMAGE></p> |
