The circuit has been designed to develop a speech filter that will improve the signal processing circuit for optimizing speech recognition. TL072 – a low noise JFET input operational amplifier with ...

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, ...

There comes a time in every electronic designer’s life when, whether they know it or not, they need an analog filter in their design. If you’re coming from a digital background, where everything is ...

Circuit VR is where we talk about a circuit and examine how it works in simulation with LT Spice. This time we are looking at a common low-frequency oscillator known as the Wien bridge oscillator.

Auto Filter is one of Live’s tried and tested effects, and is (mostly) based on emulation of hardware filters. Not only shaping the frequency spectrum, a filter can also bring a repetitive sound to ...

Q: I have a wireless telephone. When the lights in the dining room are turned on with a dimmer control, a loud static is heard on the phone. Is there a way to eliminate this interference? A: There are ...

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 ...
