COSC60 Flashcards
a type of electronic system or device that processes and manipulates digital signals or discrete data rather than continuous analog signals
digital systems
it is represented using binary digits
information
it is often referred to as “bits”
information
it can have two possible values
bits
what are the two possible values of bits?
1 and 0
they are used to represent various types of data, such as numbers, text, images, audio, and more
bits
Digital systems use binary code, which is a combination of zeros and ones, to represent information
uses binary code
Digital systems are more accurate than analog systems because the information is represented in a precise and consistent manner
accuracy
Digital systems are capable of processing large amounts of data quickly and accurately
processing speed
Digital systems are immune to noise and interference, which means that the transmitted information is less likely to be corrupted
noise immunity
Analog systems use continuous signals to represent information, such as electrical voltages or sound waves
uses continuous signals
Analog systems are better suited for representing real-world phenomena such as sound and light, which are continuous in nature
real-world representation
Analog systems provide smooth and continuous transitions between different values, which can be important in certain applications such as music or video
smooth transitions
Analog systems can be more complex than digital systems due to the need for additional circuitry to process and transmit the signals
complexity
it involves specifying subsystem characteristics and their interconnections
system design
it determines how to connect logic building blocks for specific functions
logic design
involves specifying component interconnections for gates, flip-flops, etc., often implemented as integrated circuits
circuit design
it is also known as digital logic circuits
Switching Circuits
Switching Circuits is also known as?
digital logic circuits
these are fundamental components of digital systems that manipulate binary signals (0s and 1s) using logical operations
switching circuits
a fundamental type of digital logic circuit in which the output depends only on the current input values and doesn’t rely on any past input values or the circuit’s internal state
combinational circuits
These circuits perform specific functions or operations based on the input data, using logical gates to generate the output
combinational circuits
another fundamental type of digital logic circuit, distinct from combinational circuits
sequential circuits
it has memory elements, which means they can store and remember information over time. This memory allows them to have an internal state, and the output of a sequential circuit depends not only on the current input values but also on past input values and the circuit’s internal state.
sequential circuits
they are fundamental building blocks of digital electronic circuits
logic gates
they are used to create more complex digital circuits and perform various logical and arithmetic operations in digital systems
logic gates
Output is 1 (true) only if all input signals are 1
AND gate
Output is 1 if at least one input signal is 1
OR gate
Output is the inverse of the input signal
NOT gate
Output is 1 if the number of 1s in the inputs is odd
XOR gate
Output is the inverse of an AND gate
NAND gate
Output is the inverse of an OR gate
NOR gate
it is a tabular representation used in logic and digital electronics to show all possible input combinations and their corresponding output values for a logical expression or a combination of logic gates
truth tables
it provides a systematic and comprehensive way to describe the behavior of logical expressions or circuits, making it easier to analyze and understand their operation
truth table
a basic mathematics needed for designing logic circuits
boolean algebra
