A digital accordion is an electronic musical instrument that uses the control features of a traditional accordion (bellows, bass buttons for the left hand, and a small piano-style keyboard (or buttons) for the right hand, and register switches) to trigger a digital sound module that produces synthesized or digitally sampled accordion sounds or ...
An artificial cardiac pacemaker, commonly referred to as simply a pacemaker, is an implanted medical device that generates electrical pulses delivered by electrodes to one or more of the chambers of the heart. Each pulse causes the targeted chamber (s) to contract and pump blood, [3] thus regulating the function of the electrical conduction ...
A remote control for a keyless entry system built into an ignition key: pressing a button on the key unlocks the car doors, while another button locks the car and activates its alarm system. A remote keyless system ( RKS ), also known as remote keyless entry (RKE) or remote central locking, is an electronic lock that controls access to a ...
A pulse generator is either an electronic circuit or a piece of electronic test equipment used to generate rectangular pulses. Pulse generators are used primarily for working with digital circuits; related function generators are used primarily for analog circuits .
Function generator. A simple analog function generator, circa 1990. A DDS function generator. Sine, square, triangle, and sawtooth waveforms. In electrical engineering, a function generator is usually a piece of electronic test equipment or software used to generate different types of electrical waveforms over a wide range of frequencies.
A logic signal generator or data pattern generator or digital pattern generator produces logic signals—that is, logical 1s and 0s in the form of conventional voltage levels. The usual voltage standards are LVTTL and LVCMOS. It is different from a "pulse/pattern generator", which refers to signal generators able to generate logic pulses with ...
Master System D-pad providing eight-directional buttons. A D-pad (short for directional pad) [a] is a flat, typically thumb-operated, directional control. D-pads are found on nearly all modern gamepads, handheld game consoles, and audiovisual device remote controls.
The main purpose of a digital pattern generator is to stimulate the inputs of a digital electronic device. For that reason, the voltage levels generated by a digital pattern generator are often compatible with digital electronics I/O standards – TTL, LVTTL, LVCMOS and LVDS, for instance.
The Accordina aka 'Chromatic Button Melodica', generally made of metal, uses the same mechanism and reeds as a traditional melodica. The keyboard is replaced with a button arrangement similar to a chromatic button accordion's keyboard. Alternative names. The melodica is known by various names, often at the whim of the manufacturer.
Ableton Live. Ableton Live, also known as Live or sometimes colloquially as "Ableton", is a digital audio workstation for macOS and Windows developed by the German company Ableton. In contrast to many other software sequencers, Live is designed to be an instrument for live performances as well as a tool for composing, recording, arranging ...
