Number Systems and Codes
This base-2 number system uses only 0 and 1.
What is binary?
This gate outputs HIGH only when all inputs are HIGH.
What is an AND gate?
This circuit selects one of several inputs and routes it to a single output.
What is a multiplexer?
This device stores one bit of data using clocked operation.
What is a flip-flop?
The number of states a counter goes through before repeating.
What is modulus?
The decimal value of 1010.
What is 10?
This gate outputs LOW only when all inputs are HIGH.
What is a NAND gate?
This circuit converts one binary input into one of many output lines.
What is a Demultiplexer?
This flip-flop copies the D input to Q on the clock edge.
What is a D flip-flop?
A MOD-8 counter counts from this decimal range.
What is 0 to 7?
The binary equivalent of decimal 15.
What is 1111?
The Boolean expression for an OR gate with inputs A and B.
What is A + B?
This circuit adds binary numbers and includes a carry output.
What is an adder?
This timing signal coordinates state changes in sequential circuits.
What is a clock or clock pulse?
In this type of counter, all flip-flops receive the clocked at different times?
This method is commonly used to represent negative binary numbers.
What is two’s complement?
This theorem states that (A + B)' = A'B'.
What is DeMorgan’s Theorem?
This document lists all possible input combinations and outputs.
What is a truth table?
Type of counters that rely on the same clock signal.
What are synchronous counters?
A common problem caused by wires connected when they shouldn't be.
What is a short?
The hexadecimal value represented by decimal 13.
What is D?
The simplified result of A + A'B.
What is A + B?
Logic circuits whose outputs depend only on present inputs.
What are combinational circuits?
This is the type of gate used at the end of a counter in order to "set" the first number in a counters range.
What is a Nandgate or 3-input Nandgate
The first thing to check when a digital circuit has no output at all.
Is it powered?
