Mileage/N consumption counting circuit

Published:2011/4/25 21:30:00 Author:Nicole | Keyword: mileage | From:SeekIC

The circuit is composed of CMOS IC. CD4527 is frequency multiplicator, it produces output pulse series, the output frequency is in direct proportion to the product of two inputs. The time is shared by the output frequency. The speed sensor is series with speed indicator cable, it feeds speed data to the clock input terminal of frequency multiplicator. transducer of oil gas flow is series with gasoline consumption line, it feeds gasoline consumption data to CLK terminal of another frequency multiplicator. LED 2 bit digital codes can display the gasoline consumption constantly, the shown nember represents the relation between gasoline consumption and mileage.
