Lesson 1.1 Part B
Vocab Card
Capacitor | An electrical device used to store electrical charge | The capacitor must be purchased with the proper voltage in order to be effective in repairing the microwave. |
Clock | Digital signal in the form of a rectangular pulse train or a square wave | A clock signal is produced by a clock generator. |
Combinational Logic | Digital circuitry in which an output is derived from the combination of inputs, independent of the order in which they are applied | This is in contrast to combinational logic, whose output is a function of only the present input. |
Cycle | A series of events that are regularly repeated in the same order | The water is cycled back into the system after it has been used. |
Datasheet | A printed specification giving details of the pin configuration , electrical properties, and mechanical profile of an electronic device | This datasheet can account the obliquity result. |
Digital Waveform | A series of logic 1s and 0s plotted as a function of time | A function signal generator is designed using digital waveform synthesis and micro controller technology. |
Dual In-Line Package | A very common IC package with two parallel rows of pins intended to be inserted into a socket of through holes drilled in a printed circuit board | |
Fuse | A protective device in the current path that melts or breaks when current exceeds a predetermined maximum value | He struck a match and ignited the fuse. |
Large Scale Integration | An IC that contains circuitry equivalent to 100 gates or more | Computers were getting smaller and more powerful due to the development of integrated circuits and large scale integration |
Logic Gate | An electronic circuit that performs a Boolean algebraic function | He had built a logic gate - to be precise, a NOR gate. |
Logic HIGH | The higher of two voltages in a digital system with two logic levels | |
Logic LOW | The lower of two voltages in a digital system with two logic levels | |
Medium Scale Integration | An IC that contains circuitry equivalent to more than 11 and less than | The first kind of circuit is made up of flip-flop and gate circuit. The second is consisted of medium scale integration. |
NOT Gate | Also called an INVERTER gate or an inverting buffer. A logic gate that changes its input logic level | Of course, this inactivation will not remove output strands already produced by the gate, so in isolation this NOT gate does not function as conveniently as an electronic NOT gate. |
OR Gate | Digital circuit that implements the OR operation | Using the device, the demonstrating and exploring experiments on logical circuit, which includes AND gate, NOT gate, OR gate, are illustrated. |
Plastic Leaded Chip Carrier | A square IC package with leads on all four sides for surface mounting on a circuit board | I put a few Plastic Leaded Chip Carrier on my circuit board in order to make the LEDs function correctly |
Printed Circuit Board | Insulating board contains conductive tracks for circuit connections. | I soldered stuff on the Printed Circuit Board |
Schottky TTL | TTL subfamily that uses the basic TTL standard circuit except that it uses a Schottky barrier code | |
Seven-Segment Display | An array of seven independently controlled light-emitting diodes or liquid crystal elements | |
Sequential Logic | Digital circuitry in which the output state of the circuit depends not only on the states of the inputs | Flip - flops are a key component and memory cells of sequential logic circuit. |
Simulation | Testing design function by specifying a set of inputs and observing the resultant outputs | The inputs employed for simulation are somewhat arbitrary, but they reflect underlying realities. |
Small-Scale Integration | An integrated circuit having 12 or fewer gates in one package | These were circuits on single chips with up to ten components on them , small-scale integration |
Solder Bridge | The unwanted formation of a conductive path of solder between conductors | |
Tinning | The process of applying a thin coat of solder to materials prior to their being soldered | Me and my partner have done a lot of tinning last week |
Toggle | To switch from one effect, feature, or state to another | I like to use the Toggle because when we switched it the LED responded to it |
Transistor | Term derived from "transfer resistor". Semiconductor device that can be used as an amplifier or as an electronic switch | Neuro-chip is a new technology of studying the electrical activities of nerve cells and advanced functions of brain, such as learning and memory by combining with field-effect transistor technique. |
Transistor-Transistor | A family of digital logic devices whose basic element is the bipolar junction transistor | |
Truth Table | A list of all possible input values to a digital circuit, listed in ascending binary order, and the output response for each input combination | My Truth Table has all of the inputs I have listed |
AND Gate | Digital circuit that implements the AND operation | With four explosive NULL gate, an asynchronous explosive AND gate is designed. |
