Quantum Harmonic Oscillator

Quantum Harmonic Oscillator

Background to classical mechanics Classical mechanics is a branch of physics that studies the motion of physical bodies. Sir Isaac Newton could come up with laws to explain the behavior of matter as far as motion is concerned. Later on, the particulate nature of matter was studied as a branch of physics. A particle of …

Voltage-Controlled Oscillator Characteristics & Applications

voltage-controlled oscillator

A voltage-controlled oscillator abbreviated as VCO is an electronic oscillator whose oscillation frequency is controlled by a voltage input. The applied input voltage determines the instantaneous oscillation frequency. Consequently, a VCO can be used for frequency modulation (FM) or phase modulation (PM) by applying a modulating signal to the control input. A VCO is also …

Sine Wave Generator

Sine Wave Generator

A sine wave generator is a class of functional generators that produce a sinusoid-shaped waveform or signal.  The sine wave is continuous with a smooth periodic oscillation. It is one of the most simple and basic waveforms. The waveform repeats itself after every 360°. Some modern sine wave generators use digital signal processors to synthesize …
