The circuit was designed to be able to obtain signals via amplitude modulation where the sensitivity and selectivity is fairly good. Amplitude Modulation AM – a method of emphasizing data on an ...

A new technical paper titled “Three-to-one analog signal modulation with a single back-bias-controlled reconfigurable transistor” was published by researchers at NaMLab gGmbH, GlobalFoundries, and TU ...

TM Technologies, a division of Medusa Scientific, announced this week that it has successfully demonstrated a “breakthrough modulation technology” that has the potential to increase data rates between ...

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.

This battery-powered, 2.4-GHz ISM-band transceiver uses DSSS modulation to achieve a wireless communications range as great as 300 m.

Pulse Width Modulation (PWM) or Pulse Duration Modulation (PDM) is a technique of converting analog signals into rectangular waveforms. The width of the waveform varies in proportion with the ...

Fundamental to all wireless communications is modulation, the process of impressing the data to be transmitted on the radio carrier. Most wireless transmissions today are digital, and with the limited ...

Earlier this year, we featured an unusual radio receiver that took the very traditional superhetrodyne design and implemented it in an unexpected fashion without any inductors, using instead a ...

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 ...
