ABSTRACT:
A meter driving system measures a period of input signals, and operates meters based on the measured period data. When no period data arrive in a preset period of time after the last period data, the lapsed time is treated as the period data so as to renew the meter indication. The meter driving system is very responsive to a signal whose frequency is gradually decreased, thereby giving the indication with little delay.
