In the world of digital electronics, an integrated circuit called the “Multiplexer” is a device often used for the selection process. Let's dig deeper into what Multiplexer is, its specifications, and how we can design one using VHDL in Modelsim. If you are new to VHDL, check out Getting Started with VLSI and VHDL using ModelSim – A Beginners Guide . What is Multiplexer? A multiplexer is a device that selects and merges together several analog or digital signals for transmission on a single line. Multiplexer has input and output ports. This combinational circuit select/switch between the available input data and map it to the output port. How to Design Multiplexer using VHDL? First, I will provide the entire code written to design the Multiplexer. The VHDL Multiplexer code is below. Library ieee; use ieee.std_logic_1164.all; entity mux_41 is port( signal data :in std_logic_vector(3 downto 0); signal select_line: in std_logic_vector(1 downto 0); signal enable: in std_logic; signal o

In India, Online Media Streaming is gaining popularity very rapidly especially due to the Global Pandemic. One more reason for this is the content that is provided on the OTT Platforms. You also get the benefit of saving your storage space as the minimum storage is used while watching online media and you can set the quality of media according to your network speed. The increased number of OTT Subscription leads Circuit Digest to find a new way of watching OTT media, through RaspberryPi .   If you don't know about RaspberryPi , it  is Linux based palm-size computer and can do all the tasks which a ‘normal’ computer can do. This is not the exact definition but this might give you some hint about it. The player we will be using to watch videos is Kodi media player .   Kodi is an open-source software media center, which allows us to access all kinds of content, including videos and music. We can run that content on any device like TV, laptop, phone, even in our Raspberry Pi. It comes

Basic Components of Electronics Electronic components are the building blocks of modern electronic devices, enabling the manipulation and control of electric currents to perform various functions. These components are essential for creating everything from simple circuits to complex electronic systems. Understanding the basic components of electronics is crucial for anyone interested in working with or learning about electronic devices and systems. 1. Resistors Resistors are passive components that regulate the flow of electric current in a circuit. They provide resistance, which limits the amount of current passing through them. This property is used to control voltage levels, current flow, and protect sensitive components from excessive current. 2. Capacitors Capacitors store and release electrical energy. They consist of two conductive plates separated by an insulating material. Capacitors are used for smoothing out voltage fluctuations, blocking direct current while
