The circuit of Figure 1 generates sinusoids down to very low frequencies with distortion in the region of 3% or less, yet has no feedback or gain-stabilizing components because none are needed. It ...

The recent Design Idea “Getting an audio signal with a THD < 0.0002% made easy,” discloses a low THD sine generator which led me to dust off a design that I had published in AudioXpress magazine [1] ...

A delta wave, also known as delta rhythm, is the normal brainwave in the encephalogram of a person in deep, dreamless sleep, occurring with high voltage and low frequency (1 to 4 Hz). If you plan to ...

Researchers have developed PanoRadar, a new tool to give robots superhuman vision by transforming simple radio waves into detailed, 3D views of the environment. In the race to develop robust ...

Sound vibrations leave the singer's mouth. The higher the pitch of the sound, the higher the frequency, or number of vibrations in a given amount of time. The sound enters the microphone, where it is ...
