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.

TOKYO--(BUSINESS WIRE)--Renesas Electronics Corporation (TSE:6723), a premier supplier of advanced semiconductor solutions, and Hitachi, Ltd. (TSE: 6510) today announced a technology collaboration to ...

Varying the voltage of a carrier or a direct current in order to transmit analog or digital data. Amplitude modulation (AM) is the oldest method of transmitting human voice electronically. In an ...

This low-cost AM transmitter is tunable from 10 to 15 MHz with the help of ½J gang condenser VC1, which determines the carrier frequency of the amplitude modulation transmitter in conjunction with ...

LED-driver circuits can be dimmed by applying a variable duty cycle (pulse-width modulation, or PWM) to the LED. PWM exploits LED behavior: At higher current levels, the LED’s light output is higher ...

The CQ36 series of digital output coreless current sensor ICs caters to the growing robotics market, which is poised to reach $40.2 billion by 2031. This series features a built-in Delta-Sigma (ΔΣ) ...

Introduced at ISSCC, New Circuit Development Enables Continuous-Time Digital Calibration of Delta-Sigma A/D Converter with World’s First Multi-Rate LMS Algorithm TOKYO--(BUSINESS WIRE)-- Renesas ...
