In binary phase-shift keying (BPSK), the phase of a carrier is changed according to the digital pulses signal. BPSK modulator is a phase modulator. Here the transmitted signal is a sinusoid of fixed amplitude. It has one fixed phase when the data is at one level and when the data is at the other level, the phase is shifted by 180 degrees. The binary phase-shift keying method … [Read more...] about Binary Phase Shift Keying (BPSK) Modulation Using cd4016 With Simulated Output Waveform

PSK Modulation Code in MATLAB | Phase Shift Keying
Binary Phase shift keying (BPSK) is one of the basic modulation schemes in which the phase of the carrier signal is varied or switched according to the input message pulses. When the modulation input is at logic 1, a finite number of cycles of a sinusoidal signal are transmitted and when the input is at logic 0, the phase of the sinusoid is changed. We have discussed in … [Read more...] about PSK Modulation Code in MATLAB | Phase Shift Keying
Pulse Width Demodulation Theory With Block Diagram and Waveform
PWM pulse can be detected using a Ramp generator and some circuit combinations. But how to detect or demodulate a Pulse Width Modulated Signal? The block diagram itself explains all the decoding principles. Waveforms at different sections of Pulse width demodulation are also given here. We have discussed the PWM generator circuit using 741 … [Read more...] about Pulse Width Demodulation Theory With Block Diagram and Waveform
MATLAB Code for AM with Modulation Index
How to generate Amplitude modulation (AM) using MATLAB? AM is a method of transmitting signals, such as sound or digital information, in which the amplitude of the carrier wave is changed according to the message signal. AM is widely used in the electronic communication field. The plotting of AM signals using MATLAB is very easy. Here we are simply adding the carrier … [Read more...] about MATLAB Code for AM with Modulation Index
GSM and GPS Based Accident Detecting Messaging System Using Arduino
Let’s make an accident detecting messaging system using Arduino. We can add this GPS vehicle tracking system to any vehicle. It will send an SMS when an accident is detected. The GPS module connected with the vehicle tracking system will locate the location and send an SMS to a predefined phone number about the accident with the geographical location where the accident … [Read more...] about GSM and GPS Based Accident Detecting Messaging System Using Arduino
