【正文】 ital circuit definition: Completes with the digital signal to the digital quantity carries onthe arithmetic operation and the logic operation electric circuit iscalled the digital circuit, or number system. Because it has the logicoperation and the logical processing function, therefore calls thenumeral logic circuit. Numeral logic circuit classification (according to function minute): 1st, binatory logic electric circuit The abbreviation bination circuit, it bees by the mostbasic logical gate electric circuit bination. The characteristicis: Output value only and then input value related, namely output onlyby then input value decision. The electric circuit has not rememberedthe function, the output condition changes along with the inputcondition change, is similar to the resistance electric circuit, likethe accumulator, the decoder, the encoder, the data selector and so onall belon
