Digital Systems
A digital system is a system that stores data in a discrete way. ... Larger amounts of data are stored as a string of these bits, which means a set of 0s and 1s together make a meaning to the system. The word digital is most commonly used in computing and electronics.

Power Amplifiers
A power amplifier is an electronic amplifier designed to increase the magnitude of power of a given input signal. The power of the input signal is increased to a level high enough to drive loads of output devices like speakers, headphones, RF transmitters etc. Unlike voltage/current amplifiers, a power amplifier is designed to drive loads directly and is used as a final block in an amplifier chain.
Phase Locked Loops
A phase-locked loop (PLL) is an electronic circuit with a voltage or voltage-driven oscillator that constantly adjusts to match the frequency of an input signal. PLLs are used to generate, stabilize, modulate, demodulate, filter or recover a signal from a "noisy" communications channel where data has been interrupted.

State Space Analysis
state space analysis of control system is based on the modern theory which is applicable to all types of systems like single input single output systems, multiple inputs and multiple outputs systems, linear and non linear systems, time varying and time invariant systems. Let us consider few basic terms related to state space analysis of modern theory of control systems.
Interfacing of peripherals in 8086
When we are executing any instruction, we need the microprocessor to access the memory for reading instruction codes and the data stored in the memory. For this, both the memory and the microprocessor requires some signals to read from and write to registers. The interfacing process includes some key factors to match with the memory requirements and microprocessor signals. The interfacing circuit therefore should be designed in such a way that it matches the memory signal requirements with the signals of the microprocessor.
C++ Streams
we have been using the iostream standard library, which provides cin and cout methods for reading from standard input and writing to standard output respectively. This tutorial will teach you how to read and write from a file. This requires another standard C++ library called fstream, which defines three new data types − Sr.No Data Type & Description 1 ofstream This data type represents the output file stream and is used to create files and to write information to files. 2 ifstream This data type represents the input file stream and is used to read information from files. 3 fstream This data type represents the file stream generally, and has the capabilities of both ofstream and ifstream which means it can create files, write information to files, and read information from files.
Message Passing
Message passing, in computer terms, refers to the sending of a message to a process which can be an object, parallel process, subroutine, function or thread. This message can be used to invoke another process, directly or indirectly. Message passing is especially useful in object-oriented programming and parallel programming when a single message (in the form of a signal, data packet or function) is sent to a recipient.
FIR Filter
In signal processing, a finite impulse response (FIR) filter is a filter whose impulse response (or response to any finite length input) is of finite duration, because it settles to zero in finite time.
Integration of hardware and firmware
What do you think of when someone says “hardware and software integration?” Most engineers probably think of hardware-software integration in terms of embedded systems (e.g., microprocessor system design and verification involving the computer architecture, operating systems, interfaces, and computer networks). “Co-verification” is a popular phrase that captures many integration issues. But there are other examples of such integration in both horizontal and vertical (e.g., automotive) markets.
