Colpitt’s Oscillator
Colpitt’s Oscillator has fairly good frequency stability, can be used for wide frequency ranges and it is easy to tune. This similar to shunt-fed Hartley’s Oscillator, except that two capacitors are used in the tank circuit instead of a tapped inductor. The frequency adjustment is possible both by varying the capacitor or inductor. Instrument comprises of 12V DC Regulated Power Supply, Circuit diagram is printed & components are mounted on front panel.
