Active filters are electronic circuits that use active components to filter out unwanted signals from a circuit.
Different types of active filters include low-pass, high-pass, band-pass, and band-stop filters.
Designing an active filter involves selecting the appropriate filter topology, choosing the cutoff frequency and gain, and selecting the appropriate active components such as operational amplifiers.
For example, a S...
Ripple power supplies are electronic devices that convert AC voltage to DC voltage with a small amount of AC ripple.
They are commonly used in electronic devices such as computers and televisions.
The ripple voltage can cause interference with sensitive electronic components.
Ripple power supplies can be regulated or unregulated.
Regulated ripple power supplies use feedback to maintain a constant output voltage.
Unregulated...

Bubble sort is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order.
Start from the first element and compare it with the next element
If the next element is smaller, swap them
Repeat this process for all elements in the array
Continue this process until no more swaps are needed
A program to print all prime numbers
Take input from user for range of numbers
Loop through the range and check if each number is prime
Print the prime numbers
Hashmap is a data structure that stores key-value pairs and allows constant time access to values based on their keys.
Hashmap uses a hash function to map keys to indices in an array.
Collisions can occur when multiple keys map to the same index, which can be resolved using techniques like chaining or open addressing.
Examples of hashmap implementations include Java's HashMap class and Python's dict type.
Inheritance is a mechanism in object-oriented programming where a new class is created by inheriting properties of an existing class.
Inheritance allows code reuse and promotes code organization.
The existing class is called the parent or superclass, and the new class is called the child or subclass.
The child class inherits all the properties and methods of the parent class and can also add new properties and methods.

Recursion is a process in which a function calls itself. Inheritance is a mechanism in OOP where a class inherits properties of another class. Heap is a region of memory used for dynamic memory allocation.
Recursion can be used to solve problems that can be broken down into smaller sub-problems.
Inheritance allows for code reuse and helps in creating a hierarchy of classes.
Heap is used for dynamic memory allocation in la...
