To get 500 Hz in the example circuit, C = 0.47 µF and R = 27 kΩ. Figure 2 shows the circuit response as PWM duty cycle versus dc control-signal level.

A novel circuit is proposed for designing a Second Generation Current Controlled Conveyor (CCCII) based Comparator and Binary Amplitude Shift Keying (BASK) modulator. Comparators find applications in ...

Amplitude Modulation and Demodulation Design This repository contains my project on Printed Circuit Board deisgn The project involves designing an Amplitude Modulator and Demodulator on a single PCB, ...

If we replace the potentiometer VR1 with an AC signal plus DC bias signal in any of the previous Figures 3 to 17, the voltage controlled attenuators can become an amplitude modulator circuit instead.

Starting from the theoretical equations and ideal characteristics of a diode, a simple equation-based rectifier model has been developed through some approximations. It comprises basic arithmetic ...

One of the key parameters determining the performance of the modulation is the Residual Amplitude Modulation (RAM). The NIR-MPX-LN-0.1 phase modulator combined with its matching RF driver DR-VE-0.1-MO ...
