10 Questions
How is the digital output of an ADC typically represented?
Two's complement binary number
What does an analog-to-digital converter (ADC) do?
Converts an analog signal into a digital signal
What type of integrated circuits (ICs) are most ADCs implemented as?
Metal–oxide–semiconductor (MOS) mixed-signal integrated circuit chips
What does a digital-to-analog converter (DAC) do?
Converts a digital signal into an analog signal
Why are most ADCs implemented as integrated circuits (ICs)?
Complexity and need for precisely matched components
Which statement about structures in C is correct?
Structures allow combining data items of different kinds.
How does defining a union in C differ from defining a structure?
Only one member can contain a value at any given time in a union.
What does the struct statement do in C?
Defines a new data type with more than or equal to one member.
What is the primary advantage of using unions in C?
Unions provide an efficient way of using the same memory location for multiple purposes.
How does a union statement define a new data type in C?
In the same way as defining a structure.
Study Notes
Analog-to-Digital Converter (ADC)
- An ADC converts analog signals to digital signals that can be processed by digital circuits and computers.
- The digital output of an ADC is typically represented as a binary code.
Implementation of ADCs
- Most ADCs are implemented as integrated circuits (ICs) due to their compact size, low power consumption, and high speed.
Digital-to-Analog Converter (DAC)
- A DAC converts digital signals to analog signals.
Structures in C
Defining a Union in C
- A union is a special data type that allows storing different types of data in the same memory location.
- Defining a union in C differs from defining a structure in that a union uses the same memory location for all members, whereas a structure allocates separate memory for each member.
The Struct Statement in C
- The struct statement defines a new data type that allows combining multiple variables of different data types into a single unit.
Advantages of Unions in C
- The primary advantage of using unions in C is efficient memory utilization, as they can store different types of data in the same memory location.
