Following the acquisition of certain assets and the complete set of intellectual property of Cakewalk Inc. From Gibson Brands on 2/23/18, BandLab Technologies announced the relaunch of SONAR as Cakewalk by BandLab - available. Mar 18, 2012 Today we are going to build a quadratic equation solver. Why Quadratic Equation Solver?-Good for home work, Saves you time and the energy! Before we Start Ok so I'm going to write this program in C, I'm using Bloodshed Dev- C/C, which is based on GCC. It doesn't matter what compiler you are using, but in my Project files, there is a.dev file. Write a program to find the roots of a quadratic equation of type ax2+bx+c where a is not equal to zero Roots of Quadratic Equation - C Programming Question CppForSchool.com. Solving quadratic equation. This C example program is to calculate the root(s) of a quadratic equation: ax 2 +bx+c=0. The program firstly asks the user to input factors a, b, and c. The root(s) is calculated based on the following conditions: -If a and b are zero, then there is no root.
Quadratic Equation Examples
The Quadrature Phase Shift Keying (QPSK) is a variation of BPSK, and it is also a Double Side Band Suppressed Carrier (DSBSC) modulation scheme, which sends two bits of digital information at a time, called as bigits.
Instead of the conversion of digital bits into a series of digital stream, it converts them into bit pairs. This decreases the data bit rate to half, which allows space for the other users.
QPSK Modulator
The QPSK Modulator uses a bit-splitter, two multipliers with local oscillator, a 2-bit serial to parallel converter, and a summer circuit. Following is the block diagram for the same.

At the modulator’s input, the message signal’s even bits (i.e., 2nd bit, 4th bit, 6th bit, etc.) and odd bits (i.e., 1st bit, 3rd bit, 5th bit, etc.) are separated by the bits splitter and are multiplied with the same carrier to generate odd BPSK (called as PSKI) and even BPSK (called as PSKQ). The PSKQ signal is anyhow phase shifted by 90° before being modulated.
The QPSK waveform for two-bits input is as follows, which shows the modulated result for different instances of binary inputs.
QPSK Demodulator
The QPSK Demodulator uses two product demodulator circuits with local oscillator, two band pass filters, two integrator circuits, and a 2-bit parallel to serial converter. Following is the diagram for the same.
The two product detectors at the input of demodulator simultaneously demodulate the two BPSK signals. The pair of bits are recovered here from the original data. These signals after processing, are passed to the parallel to serial converter.
