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…
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…
Our everyday lives have benefited greatly from wireless communication, which allows devices to communicate and exchange data without the use of physical cords. 915 MHz and 433 MHz are two well-liked frequency ranges for wireless communication. Remote controllers and IoT…
SNR is a crucial statistic in various industries, evaluating signal strength and dependability for various applications. This is commonly represented by decibels (dB). Converting SNR to dB is straightforward, providing a practical way to express and contrast signal strength against…
At colleges, it’s a busy time now as I can see a lot of my friends running around to get their engineering major projects approved (Luckily mine got approved ?). Here at circuitsgallery.com we already have a fine collection of mini-projects on electronics and communication….
