CDA Centre Interview Questions and Answers

SPI (Serial Peripheral Interface) is a synchronous serial communication protocol commonly used in embedded systems.

• SPI is a full-duplex communication protocol, meaning data can be sent and received simultaneously.

• It uses four wires for communication: MISO (Master In Slave Out), MOSI (Master Out Slave In), SCK (Serial Clock), and SS (Slave Select).

• SPI devices are typically classified as master or slave, with the master ...read more

A microcontroller is a compact integrated circuit designed to perform specific tasks, while a processor is a general-purpose device used for executing instructions.

• Microcontrollers typically have built-in memory and peripherals, while processors require external components for operation.

• Microcontrollers are commonly used in embedded systems like IoT devices and consumer electronics, while processors are found in comput...read more

Multiplexing in digital domain involves combining multiple signals into one signal for transmission over a single channel.

• Multiplexing allows for efficient use of bandwidth by combining multiple signals into one

• Types of multiplexing include time-division multiplexing (TDM) and frequency-division multiplexing (FDM)

• Example: TDM divides time into slots for each signal to transmit data sequentially
