Title: Device for increasing of resolution of signal
Inventor: BUERUNAA TSUINMAAMAN
IPC: G01P3/481
Filed: 1993-06-24
Abstract: PURPOSE: To improve the resolution of number of revolution signals. CONSTITUTION: The period length of a signal from a number of revolution sensor 105 is measured by means of first and third counters 120 and 130 which are cascade-connected with each other, in accordance with the clock frequency of an oscillator 115. The third counter 130 has the count value corresponding to the periodic length of the sensor signal. When the value is loaded into a second counter 140 and the count value of the counter 140 becomes zero as the clock frequency is subtracted from the value, a drive signal is generated from the output of the counter 140 and inputted to an engine controller 100.
