What numbering formats are really codes rather than true number systems?

a- binary%26amp;octal


b- hexadecimal %26amp;octal


c-decimal %26amp; binary


d- BCD and ASCII

If one input of an OR gate is HIGH while the other is a block signal, the output is...???





a- a clock signal


b- LOW


c- HIGH


d- can't determine??What numbering formats are really codes rather than true number systems?
Binary, octal, decimal, and hexadecimal are number systems with bases 1, 8, 10, and 16 respectively. The C in BCD and ASCII stands for coded so the answer to the first question is d.





If either input of an OR gate is tied high the output of the gate will be high regardless of the signal on the other input (refer to a truth table for an OR gate to confirm for yourself.) The answer to the second question is c.What numbering formats are really codes rather than true number systems?
d - BCD %26amp; ASCII are coding


';block signal';?
