Modulation is the act of translating some low-frequency or baseband signal (voice, music, and data) to a higher frequency. Why do we modulate signals? There are at least two reasons: to allow the ...

A scheme of simple band-pass RC- and LR- filters on operational amplifiers containing only one capacitor or inductor and 3 resistors is proposed. A comparison is made of the amplitude-frequency ...

Helium leaks are hard to detect. Helium is odorless, colorless, tasteless, and does not react with other chemical substances.

What you need to know about understanding frequency response curves of loudspeakers. Note: Paul Dicomo was a great friend to eCoustics and many of us over the past 2 decades. Sadly, Paul lost a ...

This white paper discusses a method for driving high-frequency sinusoidal ripple over capacitive loads for power supply rejection ratio (PSRR) testing, an important performance parameter for many ...

Researchers at Nanjing University have developed a novel helium-detecting device, drawing inspiration from the traditional ...

Amplitude, the well-funded product intelligence startup that helps businesses use their data to predict which features will drive the best business outcomes for them, today announced that it has ...
