The oscillator is designed to have a small-signal loop gain greater than one. The higher gain allows an oscillator to start by exponentially amplifying some ever-present noise. [11] As the peaks of the sine wave approach the supply rails, the saturation of the amplifier device flattens (clips) the peaks, reducing the gain.
Simple relaxation oscillator made by feeding back an inverting Schmitt trigger's output voltage through a RC network to its input.. An electronic oscillator is an electronic circuit that produces a periodic, oscillating or alternating current (AC) signal, usually a sine wave, square wave or a triangle wave, [1] [2] [3] powered by a direct current (DC) source.
A basic Direct Digital Synthesizer consists of a frequency reference (often a crystal or SAW oscillator), a numerically controlled oscillator (NCO) and a digital-to-analog converter (DAC) [5] as shown in Figure 1. The reference oscillator provides a stable time base for the system and determines the frequency accuracy of the DDS.
VCOs can be generally categorized into two groups based on the type of waveform produced. [4]Linear or harmonic oscillators generate a sinusoidal waveform. Harmonic oscillators in electronics usually consist of a resonator with an amplifier that replaces the resonator losses (to prevent the amplitude from decaying) and isolates the resonator from the output (so the load does not affect the ...
The VTech Socrates is an 8-bit educational home video game console manufactured and released in 1988 by VTech. The console features a robot character Socrates, named after the philosopher. The character is similar to Johnny Five from the Short Circuit movies. It was discontinued in 1994.
The APF Microcomputer System [2] is a second generation 8-bit cartridge-based home video game console released in October 1978 by APF Electronics Inc. with six cartridges. [3] The console is often referred to M-1000 or MP-1000, which are the two model numbers of the console. The APF-MP1000 comes built-in with the game Rocket Patrol.
In the 1980s, video games in East Germany were to introduce children and young people to technology and show that the GDR was a progressive country. [ 1 ] [ 2 ] [ 3 ] The BSS 01 was manufactured between 1979 [ 4 ] and 1981 [ 5 ] by the to the Kombinat Mikroelektronik Erfurt belonging VEB Halbleiterwerk Frankfurt (Oder) [ 6 ] [ 7 ] [ 8 ] as a ...
PICO-8 is a virtual machine and game engine created by Lexaloffle Games. It is a fantasy video game console [3] that mimics the limited graphical and sound capabilities of the old 8-bit systems of the 1980s to encourage creativity and ingenuity in producing games without being overwhelmed with the many possibilities of modern tools and machines.
