Title: Digital noise elimination system
Inventor: KAWANO HISATO
IPC: G11B20/18
Filed: 1991-03-08
Abstract: PURPOSE:To reduce the capacity of a storage element and to utilize the memory effectively by providing a counter, a count latch section and a comparator and latching a current input data as an output data when the comparator detects coincidence. CONSTITUTION:When a change is caused in an input data, a count latch section 6 stores the count at that time. When an input data is not changed afterward, a switch section 5 is thrown to the lower position, the count of a counter 4 is advanced as 1, 2... for that time, then a 2nd comparator 7 makes comparison, but the end comparator 7 does not make immediate coincidence. When the input data is not changed and the count of a counter 4 reaches 0 after (n-1), a coincident output is generated from the comparator 7 and an output latch section 8 is driven. The input data is latched and an output data is generated at that time. If the preceding input data is changed before the counter 4 reaches 0, a new count is stored in the latch section 6 and the content is changed, then no coincident output is generated from the comparator 7 and the data inputted so far is deleted as noise.
