Title: A device and a method for generating a time mean value-free binary signal
Inventor: ERIK MATTISSON SVEN
IPC: H03K5/08
Filed: 1998-07-10
Abstract: THE PRESENT INVENTION RELATES TO GENERATION OF A TIME MEAN VALUE-FREE BINARY SIGNAL (0) FROM AN INPUT SIGNAL (IN). SAID DEVICE (10) COMPRISES A FEED-BACK LOOP ADJUSTING THE PULSE RATIO OF THE OUTPUT SIGNAL BY COMPARING ITS MEAN VALUE TO THE MEAN VALUE OF A TIME MEAN VALUE-FREE REFERENCE SIGNAL (J) AND FEED-BACK THE DIFFERENCE BETWEEN SAID TWO MEAN VALUES. SAID MEAN VALUES ARE APPROXIMATED BY LOW PASS FILTERING SAID BINARY SIGNAL (O) AND SAID REFERENCE SIGNAL (J) WITH TWO FILTERS (8, 7). IF SAID FILTERS (8, 7) ARE NON-LINEAR, THE MEAN VALUES OF SAID FILTERED SIGNALS (S, FJ) CAN DEVIATE FROM THE MEAN VALUES OF SAID REFERENCE SIGNAL (O) AND SAID REFERENCE SIGNAL (J). BY CONSTRUCTING SAID FILTERS (8, 7) AS REGARDS NON-LINEARITIES, TO BE EQUAL, SAID AFOREMENTIONED DISCREPANCY WILL BE COMPENSATED, SINCE SAID SIGNALS WILL DEVIATE BASICALLY TO THE SAME DEGREE FROM THEIR THEORETICAL VALUES, WHEN TIME MEAN VALUE FREE.
