Over the past decades, engineers have introduced numerous technologies that rely on light and its underlying characteristics.

Neuroimmune modulation inhibited progression of structural damage in patients with rheumatoid arthritis who had inadequate response or intolerance to DMARD therapy, according to data presented at ACR ...

Modulation is fundamental to electronic communications. The modulating signal might be analog in nature (voice or music) or digital bit streams. Most modern communication systems are digital, using ...

[brmarcum] takes us back to analog building block basics with his Frequency Modulation and Demodulation tutorial. Frequency Modulation (FM) sounds simple at first, but understanding the electronics ...

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 ...

[esot.eric] was trying to drive a motor and naturally thought of using pulse width modulation (PWM) to control the motor speed. However, he found that even with a large capacitor, his underpowered ...

Neuroimmune modulation could be an “emerging therapeutic approach” for patients with rheumatoid arthritis who had incomplete response or intolerance to anti-TNF therapy, according to Minna Kohler, MD, ...

For driving an antenna, efficient generation of a clean and stable signal is required for optimum performance of many systems. This paper focuses on methodologies to efficiently apply a pure, ...

First I’ll tell what you already know. Back in the day, AM broadcasting was king and FM was commercial-free. Things changed in the 1970s as FM grew in popularity. Here we are 40+ years later with many ...
