From that page, we present the sketch in Figure 6. Figure 6 A square wave and its Hilbert transform, bringing about a 90° phase shift of each frequency component of the input signal in its own time ...

In an advance in microsensor technology, researchers have unveiled an ultra-sensitive gas detection method using surface ...

A standard electret microphone can detect sub-audio "sounds" when some simple equalization circuitry is added.

Everything you wanted to know about (re-)mastering audio, but were afraid to ask. Audio engineers help explain the art and ...

“Gravitational wave detection is an incredibly delicate science,” Souradeep explained. Even the faintest ground vibration from traffic, wind or wildlife can disrupt a signal. “The site ...

This project generates a square wave signal using Timer1 on an Arduino. The frequency of the square wave can be adjusted via serial input, making it a versatile tool for signal generation and testing.

In one 20-year-old tree, researchers noticed sharp, square-wave-like bioelectrical spikes hours before the eclipse. These signals vanished immediately after the event, creating a clear boundary in the ...

As I showed in another recent paper, it is impossible to block or dissipate gravitational wave signals. They offer the optimal communication ... divided by the speed of light squared times the square ...
