While that’s not necessarily a problem, it does mean that we, as humans, have a few shortcomings that we can’t overcome. Namely, we experience a phenomenon calledauditory masking. Exactlyhowthis works in totality is quite complex, but the long and short of it is: if there is a loud ...
Attenuation is the opposite of amplification. If you turn the volume down on your radio, it’s reducing the amplification of the signal, not attenuating it. The same signal may be attenuated by a filter that removes all unwanted signals above a certain frequency. A low pass filter lets all ...
as shown in Figure 1. I've simplified the schematic to show only the output device, which is where the differences between the classes are defined. In a simple amplifier like this, the audio input signal — a small alternating current (AC) — flowing into the base ...
The best signal conditioners provide electrical isolation between the inputs and their outputs. Isolation reduces noise, prevents ground loops in the measuring chain, and ensures accurate measurements. Sometimes also referred to asgalvanic isolation, electrical isolation is the separation of a circuit fro...

In the tissues of exposed species, micro- and nano-fragments accumulate, leading...
What Are the Key Chemical Properties of NO Relevant to Biology? How Is NO Made in Biological Systems? How Does the Biochemistry of NO Change with Concentration? What Is the Fate of NO, and How Does That Change Its Biochemistry? How Does NO Act as a Signaling Molecule? How Do We Translat...
Without going into too much depth concerning the biology of the structure of the ear, what happens next is that the rapidly changing pressure waves in the air are transferred, via the external ear and ear canal, to the eardrum, which in turn passes them along via the ear bones (you know...
They were capable of impressive punch and dynamic reach - in part thanks to their metal drivers, which were rare at the time. They also weren't limited to one decade, evolving over several years and several variations to inspire what is today one of our favourite active speakers, the ...
You can cover amplification by connecting sources straight into active speakers, which have amplifiers built into the cabinets, or by opting for a pre/power amplifier pairing where the necessary preamp and power amp duties are housed in separate boxes. But the most simple, convenient, space-effici...
Biology and medicine:In biology and medicine, photonic technologies are enabling greater patient safety, more favorable outcomes, and earlier detection of disease. Photonic technologies such as endoscopy and optical coherence tomography (OCT) enable minimally invasive surgeries and microsurgeries that allow...
