In many ways, the Colpitts oscillator is the exact opposite of the Hartley Oscillator we looked at in the previous tutorial. Just like the Hartley oscillator, the tuned tank circuit consists of an LC resonance sub-circuit connected between the collector and the base of a single stage transistor amplifier producing a sinusoidal output waveform.

Jul 09, 2015· The zero EMF induced at the positions A & E. Similarly, at 900 and 2700 of phase, the sine wave will have the maximum amplitude. It occurs at C & G. At other positions of the sine wave (B, D, F, H) the EMF will be as per the formula, e = Vmax*sinθ. The EMF value of the sine wave with respect to the phase angle of the moving coil is given below.
signal, often a sine wave or a square wave . A low-frequency oscillator (LFO) is an electronic oscillator that generates an AC waveform between 0.1 Hz and 10 Hz. This term is typically used in the field of audio synthesizers, to distinguish it from an audio frequency oscillator. Types of electronic oscillator
The oscillators are electronic circuits makes a respective electronic signal generally the sine wave and the square wave. It is very important in other types of the electronic equipment such as quartz which used as a quartz oscillator. The amplitude modulation radio transmitters use the oscillation to generate the carrier waveform.
Sine Wave Generator Is Crystal Accurate Abstract: This application note discusses how to gain greater accuracy and less drift by deriving a sine wave from a digital source. This results in a stable, frequency-accurate since wave, which is ideal for servos, test equipment, and telecommunications systems.
The Bubba Oscillator – An Op Amp Sine Wave Generator 3 total harmonic distortion is an important factor and must be kept low. The full schematic for the Bubba oscillator can be seen in figure 2. The most important equation when working with this circuit is the one that relates how the oscillation frequency depends on the values for R and C.
That sine wave, having a finite and easily computed slope, along with some noise floor in the internal circuitry that DOES square up the resonator signal, cause a predictable phase noise or time jitter. Use the formula. T jitter = V noise / SlewRate. to predict the timing wander of this clock source.
More NFB will damp the oscillation, critical NFB will have a sine wave output and less NFB will have a square wave output. The two Zener diodes connected face to face is to limit the peak to peak output voltage equal to twice of Zener voltage. It is very flexible to construct the Op. Amp. crystal oscillator due to high amplifier gain

Crystal Sine Wave Oscillators. Where good frequency stability is required, in applications such radio transmitters, basic LC oscillators cannot guarantee to hold their frequency without some drifting, which can be caused by quite small changes in supply voltage (although stabilised power supplies help avoid this) and changes in temperature.
Sine wave oscillators are used as references or test waveforms by many circuits. A pure sine wave has only a single or fundamental frequency—ideally no harmonics are present. Thus, a sine wave may be the input to a device or circuit, with the output harmonics measured to determine the amount of distortion.

The sine wave is a naturally occurring signal shape in communications and other electronic applications. Many electronic products use signals of the sine wave form. Audio, radio, and power equipment usually generates or processes sine waves. As it turns out, there are literally dozens of ways to generate a sine wave.
Sinusoidal Oscillators 365 14.1 Sinusoidal Oscillator An electronic device that generates sinusoidal oscillations of desired frequency is known as a *sinu-soidal oscillator. Although we speak of an oscillator as "generating" a frequency, it should be noted that it does not create energy, but merely acts as an energy converter.
