ABSTRACT:
There is shown and described a relatively simple electronic circuit using few discrete components which is used to replace the filter and delay line differentiator in existing circuits. The new circuit provides a simultaneous output of even and odd signals which have the same transfer function except for the derivative operation. The circuit is especially useful in read and write channels of a disk drive apparatus.
