<p>Method and apparatus for producing pulses in accordance with the change of a physical quantity, wherein each time an electric pulse is produced, the value of the physical quantity is sampled and held; and each time the physical quantity has changed by a prdetermined reference amount with respect to the sampled and held value thereof, one output electric pulse is produced to cause the sampled and held value to be replaced by the value of the physical quantity at that time; and the above operations are repeated to produce a series of output pulses whose number corresponds to the amount of change of the physical quantity. By counting the number of the output pulses it is possible to know the amount of change, and by changing the reference amount it is possible to change the interval or density of the output pulses thereby to change the resolution. <IMAGE></p> |
