The restriction is on the derivative of the amplitude, not on the amplitude itself. Added citation from analog devices and clarified by adding "slow-changing". undo Tag: Visual edit

curprev 21:1721:17, 29 June 2023‎ Em3rgent0rdr talk contribs‎ 9,980 bytes +115‎ I think is easier to comprehend these two states as "↗" or "↘" where ↗ state is a positive voltage (like +1 V) and ↘ has a negative voltage (like -1 V), instead of calling them 1 and 0. Cause the integration operation works with +1 and -1. undo Tag: Visual edit
