The Inductor L, capacitor C, and Resistor R are the analogous of mass, the compliance (reciprocal of spring constant), and the viscous damping factor of the mechanical system.Just like the Hartley oscillator, the tuned tank. Determine the (i) operating frequency and (ii) feedback fraction for Colpitt’s oscillator shown in Fig. In many ways, the Colpitts oscillator is the exact opposite of the Hartley Oscillator we looked at in the previous tutorial. Find the capacitance of the capacitor required to build an LC oscillator that uses an inductance of L1 1 mH to produce a sine wave of frequency 1 GHz (1 GHz 1 × 1012 Hz).

in electronic oscillator circuits to make remarkably accurate timepieces. In crystal oscillator, the crystal is suitably cut and mounted between two metallic plates as shown in the figure. The solution for the current in a given loop takes the form i i0 cos(t.Quartz is inexpensive, naturally available, and mechanically strong when compared to others.These oscillators are made of Quartz crystal Rochelle salt and Tourmaline.The limiting case is (b) where the damping is (b 4 m k ). (a) If the damping is small (b < 4 m k ), the mass oscillates, slowly losing amplitude as the energy is dissipated by the non-conservative force (s). It is these vibrations that eventually get converted into oscillations. 4: The position versus time for three systems consisting of a mass and a spring in a viscous fluid.It operates on the principle of the inverse piezoelectric effect in which alternating voltage applied across the crystal surfaces causes it to vibrate at its natural frequency.
