Unit 1
An electrical device used to store electrical charge.
WHAT ARE CAPACITORS?
An electrical device used to store electrical charge.
Capacitor
Delay from the time a signal is applied to the time when the output makes its change
Propagation delays
When both inputs of a J-K flip-flop cycle, the output will:
TOGGLE
An integrated circuit having 12 or fewer gates in one package.
Small-Scale Integration (SSI)
Electronic test equipment that can perform multiple tasks. Typically one capable of measuring voltage, current, and resistance. May also measure capacitance, inductance, current gain of transistors, and/or anything else that can be measured electronically.
Digital Multimeter
The difference in electrical potential energy between two places in a circuit.
Voltage(V)
Digital circuit that accepts binary data from some input sources and then shift the data through a chain of flip flops one bit at a time.
Shift Register
Convert 11001001(binary) to decimal.
201
An IC that contains circuitry equivalent to more than 11 and less than 100 gates.
Medium Scale Integration (MSI)
An almost instantaneous rise and decay of voltage or current in a periodic pattern with time and with a constant peak value.
Square Wave
The current in a circuit equals the voltage difference divided by the resistance
Ohm's Law
If base current is 100µA and current gain is 100, then collector current is
10mA
A sequential circuit based on a latch whose output changes when its CLOCK input receives a pulse.
Flip-Flop
The number of complete waves that pass a given point in a certain amount of time (f = 1/T)
Frequency
TTL-compatible IC that can be wired to operate in several different modes, such as a one-shot and an astable.
555 Timer
The algebraic sum of all voltages around any closed path must equal zero.
Kirchoff's Voltage Rule
Counter in which all of the flip-flops are clocked simultaneously.
Synchronous Counter
Digital circuitry in which the output state of the circuit depends not only on the states of the inputs but also on the sequence in which they reached their present States
Sequential Logic
Fraction of the total period that a digital waveform is in the HIGH state. DC = th/T (often expressed as a percentage: %DC = th/Tx100%).
Duty Cycle (DC)
One that has only one path current.
Series Circuit
Logic circuit that operates like an OR gate followed by an INVERTER. The output of a NOR gate is LOW (logic level 0) when any or all inputs are HIGH (logic level 1).
NOR GATE
A graphical tool for finding the maximum SOP or POS simplification of a Boolean expression. A Karnaugh map works by arranging the terms of an expression so that variable scans are cancelled by grouping minterms or maxterms.
K Mapping
A synchronous sequential circuit, consisting of a sequential logic section and a combinational logic section, whose outputs and internal flip-flops progress through a predictable sequence of states in responds to a clock and other input signals.
State Machine
1) Theorem stating that the complement of a sum (OR operation) equals the product (AND operation) of the complements
2) Theorem stating that the complement of a product (AND operation) equals the sum (OR operation) of the complements.
