  • Abstract
    A proposed a.c. digital watt/joule meter is described, which combines the principle of the well known dual-slope analogue-digital convertor with that of the sampling digital wattmeter to provide a system where multiplication, digitising, averaging and integration may be performed by using relatively few components.
