logic low造句

• The model assumes one line or node in the digital circuit is stuck at logic high or logic low.
• If any of the logic gates becomes logic low ( transistor conducting ), the combined output will be low.
• Since the start bit is logic low ( 0 ) and the stop bit is logic high ( 1 ) there are always at least two guaranteed signal changes between characters.
• Bubble error correction is a digital correction mechanism that prevents a comparator that has, for example, tripped high from reporting logic high if it is surrounded by comparators that are reporting logic low.
• Forcing the 21st address line ( the actual logic signal wire coming out of the chip ) to a logic low, representing a zero, results in a modulo-2 ^ 20 effect to match the earlier processors'address arithmetic, but the 80286 has no internal capability to perform this function.
• Each character is sent as a logic low start bit, a configurable number of data bits ( usually 8, but users can choose 5 to 8 or 9 bits depending on which UART is in use ), an optional parity bit if the number of bits per character chosen is not 9 bits, and one or more logic high stop bits.
• :It is the nominal supply voltage ( actually 5v + /-0.25V ) that will guarantee a logic low of < 0.8 v and a logic high of between 2.0 V an 5 v with all the tolerances of the circuit and output loading etc . It does depend upon the internal design of the logic gates.
