To compose a speculative music is first to draw associations with the medieval category of a “musica speculativa”, that esoteric part of music theory that lies beyond the practical and theoretical aspects of musical composition to address existential questions of “why?” 1 It was during this...
A spectrum analyzer is a device that measures and displays Signal amplitude (strength) as it varies by frequency within its frequency range (spectrum). The frequency appears on the horizontal (X) axis, and the amplitude is displayed on the vertical (Y) axis. It looks like anoscilloscope, and...
Near Infrared (NIR) Spectroscopy is an analytical technique used across a wide range of sectors and industries. Click to read more...
spectral line broadening, which embraces both shapes and shifts of spectral lines, is of both fundamental and practical importance. On the fundamental side, the study of the spectral line profiles reveals the underlying atomic and molecular interactions. On the practical side, the spectral line ...
Spacer by Spectral Plugins:Spectral Plugins is a manufacturer that unfortunately ceased operations, but upon doing so they made the generous decision to perpetually offer all their plugins for free. Originally $119, Spacer provides advanced capabilities including algorithmic, convolution, and granular reve...
2. Figure 2 shows the quantum efficiency of standard InGaAs in blue together with the quantum efficiencies of two extended wavelength alloys, X=0.74 (green) and X=0.82 (red). The spectral response of silicon is also shown. As we like to say, "InxGa1-xAs starts where silicon leaves off...
To prepare for capillary electrophoresis, a spectral calibration with the corresponding matrix standard for the selected group of dyes must be performed on the genetic analyzer in order to accurately detect the dye-labeled primers. Each unknown sample is mixed with the size standard and fo...
Figure 3: Gaussian filtered signal and GFSK modulated signal response This method of filtering reduces sideband power or out-of-band spectrum, interference due to adjacent channels and the spectral width or bandwidth of FSK signal. However, this reduction in spectral width causes a spread in the ...
If you've ever shopped for speakers or headphones, you've probably come across the term "frequency response" in the product specs. This is one of the key measurements that determines how a speaker or headphone will sound. But what exactly does it mean and why does it matter?
When using a keyboard is impractical or dangerous–such as while driving–users can issue spoken demands or dictate messages. Voice-activated telephone response systems can process complex requests without requiring users to navigate menus. People with disabilities who are unable to use other input mea...
