A circuit that produces alternating and continuous waveforms is known as an oscillator. The waveform can be a sine wave, square wave, etc. based on their output frequency, oscillators are divided into various types. Electronic Oscillators' frequency can be controlled by their input voltage, so they are termed voltage-controlled oscillators. There are many types of oscillators but mainly divided into two categories. One is Harmonic Oscillators or Linear Oscillators and the second one is … [Read more...]
What is RC Phase Shift Oscillator : Circuit Diagram & Its Working
An oscillator is a mechanical or electrical construction that produces oscillation based on some variables. This oscillator is used from clock to various metal detectors and even on computers where microprocessors and microcontrollers exist The oscillator in which the RC circuit is used as a feedback path is the RC phase shift oscillator. It generates stable sine waves that are used in low-frequency generations, particularly in the audio frequency range. The amplifier provides a phase shift of … [Read more...]
What is Hartley Oscillator : Working and Its Applications
An electronic oscillator in which the oscillator frequency is determined through a tuned circuit consisting of inductors and capacitors is called the Harley oscillator. The invention of the Harley oscillator circuit was done in 1915 by Ralph Hartley, an American engineer. This oscillator is a type of harmonic oscillator. The Hartley Oscillator produces the waves of radio frequencies therefore it is also referred to as radiofrequency oscillators. The tank circuit of the oscillator having a … [Read more...]
What is an RC Oscillator : Circuit & Its Working
An oscillator is used to produce periodic oscillating signals in an electronics circuit. The oscillations are mainly produced in the form of a square wave or sine wave. The oscillators can convert DC to AC and used in a number of electronic devices like clock generators, digital instruments like calculators. The oscillating signals are used in television transmitters, wall clocks, radios, and many more. A feedback oscillator is a type of oscillator in which the output signal is feedback into the … [Read more...]
