This amplitude modulation circuit design using BC547 transistor is perfect for students learning how to build AM modulator circuits. The circuit demonstrates the fundamental principle of AM generation ...
Abstract: Amplitude modulation (AM) is widely used for not only wireless ... it can be employed for AM in place of analog multiplier. This brief presents AM circuit using varactor diode of simple ...
Abstract: This paper presents three pulsewidth modulation modulators using CMOS operational transconductance amplifiers. They consist of a ramp integrator and current-tunable Schmitt triggers.
Unfortunately, the input stimulus remains unidentified for the majority of these circuits. Therefore, development of a synthetic method for stimulus-independent modulation of these circuits is highly ...
In this project, QFT is implemented using quantum circuits that employ a series of quantum gates. The gates used include the Hadamard gate for creating superpositions and phase rotation gates for ...
Simulation of FM, DSB-SC, DSB-LC and SSB-SC modulation and demodulation techniques in MATLAB with noise analysis and threshold effect demonstration.
