The Digital Sketchbook Arduino Frequency Measurement Library
Software on a MacBook Pro includes Laidman & Katsura's WaveWindow, which functions as a software oscilloscope. It is beneficial for individuals working with sound on the Mac, offering an educational and entertaining experience. Additionally, Faberacoustical's Signal Scope allows for the...
Colpitts oscillator
The Colpitts circuit, similar to other LC oscillators, consists of a gain device (such as a bipolar junction transistor, field effect transistor, operational amplifier, or vacuum tube) with its output connected to its input in a feedback loop that contains...
Signal Detecting Auto Power-On Unit
How many times have you wished that there was a simple way to turn on that sub-woofer or some other piece of audio equipment, simply by sending it a signal? This ability is fairly common in commercial subs and some...
Lc-checker
The circuit is based on the grid-dip or absorption effect, which occurs when a parallel resonant circuit is coupled to an oscillator of the same frequency. Q1 operates in a conventional Colpitts oscillator circuit at a fixed frequency of approximately...
grid frequency
Wall sockets provide power in the form of a 230-volt sine wave, operating at a frequency of 50 hertz. This means that the voltage alternates between positive and negative at a rate of 50 full cycles per second. Different countries...
