SanDisk India Device Design Centre Interview Questions, Process, and Tips

A process is an instance of a program, while a thread is a unit of execution within a process. Threading in Linux allows for concurrent execution.

• A process is an independent entity that can be scheduled and allocated resources by the operating system.

• Threads are lightweight units of execution within a process that share the same memory space.

• Threading in Linux is implemented using the clone() system call.

• Threads in Lin...read more

OOP concepts in C++

• Encapsulation: bundling of data and methods into a single unit

• Inheritance: creating new classes from existing ones

• Polymorphism: ability of objects to take on many forms

• Abstraction: hiding unnecessary details and exposing only essential features

• Encapsulation example: class with private data members and public methods

• Inheritance example: derived class inheriting properties and methods from a base class

A function to print the reverse of a given string.

• Create a function that takes a string as input.

• Initialize an empty string to store the reversed string.

• Iterate through the characters of the input string in reverse order.

• Append each character to the reversed string.

• Print the reversed string.

The 15th bit of the hexadecimal number 0x12345678 is 0.

• To find the 15th bit, convert the hexadecimal number to binary.

• Counting from right to left, the 15th bit is the 2nd bit from the left.

• In this case, the 15th bit is 0.

A low pass analog filter is designed to allow low frequency signals to pass through while attenuating high frequency signals.

• Determine the cutoff frequency for the filter

• Choose a suitable filter design method (e.g., Butterworth, Chebyshev, etc.)

• Select the appropriate order for the filter

• Design the filter circuit using passive components (resistors, capacitors, inductors)

• Simulate and test the filter response using softw...read more

A capacitor is an electronic component that stores and releases electrical energy. An inductor is a coil that stores and releases magnetic energy.

• Capacitor: Stores electrical energy and releases it when needed.

• Inductor: Stores magnetic energy and releases it when needed.

• Capacitors are commonly used in electronic circuits to smooth out voltage fluctuations.

• Inductors are used in applications such as transformers and elec

An inverter is a device that converts DC power to AC power, allowing for the use of AC appliances.

• An inverter uses electronic components to convert the direct current (DC) from a power source, such as a battery or solar panel, into alternating current (AC).

• It typically consists of a rectifier, which converts AC to DC, and an inverter circuit, which converts DC back to AC.

• The inverter circuit uses switches, such as tran...read more
