Title: Method and device for processing program
Inventor: NISHIZAWA OSAMU
IPC: G06F9/48
Filed: 2001-06-08
Abstract: PROBLEM TO BE SOLVED: To quickly respond to an input signal, where a single impulsive noise is generated, without receiving an influence of the noise to process a program. SOLUTION: A voltage level Vin of an input signal 1 is compared with a preliminary reference level L1 and a discrimination reference level L2. When the input signal 1 rises (falls), it first reaches the preliminary reference level L1 (the level L2 in the case of fall), and processing of the program is started. Counting of an elapsed time T is also started. When the voltage level Vin of the input signal 1 exceeds the discrimination reference level L2 (the level L1 in the case of fall) at reaching the elapsed time T, processing of the program is continued. In the case that only the single impulsive noise 2 is inputted, processing of the program is invalidated because the signal level after the time T is reduced (elevated in the case of rise), and thus a malfunction can be prevented.
