Scientists have hypothesized for decades about how the brain filters out distractions, but it has been challenging to find evidence to support the theories. Now, researchers have identified a neural ...

Butterworth filter is a type of filter whose frequency response is flat over the passband region. Low-pass filter (LPF) provides a constant output from DC up to a cutoff frequency f(H) and rejects all ...

This subwoofer active filter circuit is a 24 dB octave filter with a Bessel character and cutoff frequency of 200 Hz. So, if you are interested in experimenting with audio circuits in subwoofer range, ...

Using brain recordings and a computer model, an interdisciplinary team confounds the conventional wisdom about how the brain sorts out relevant versus irrelevant sensory inputs in making choices.

This video explains how capacitors work and why they are essential in modern electronics. Capacitors store and release ...

This video explains how inductors work and how they store energy in a magnetic field when electrical current flows through them. Inductors are passive components used to resist sudden changes in ...
