 | Astable multivibrator Design and set up an astable multivibrator and calculate the time period and duty cycle of the output wave form. |
| Melde's String Apparatus Aim is to determine the frequency of electrically maintained tuning fork. |
| Kundt's Tube Apparatus Kundt's tube is a device used to calculate the velocity of sound through a metal rod. Also the Young's modulus of the rod can be calculated. |
| Ultrasonic Interferometer Ultrasonic Interferometer is a device used to calculate the velocity of ultrasonic sound through different liquid media. |
| Doppler Effect The Doppler Effect is the perceived change in frequency of sound emitted by a source moving relative to the observer.The effect was first noted by Christian Doppler in 1842. |
| A.C Sonometer Every object has a natural frequency of vibration. If kinetic energy is applied to an object at a rate that matches its natural frequency, resonance occurs and the object vibrates. In this experiment a small current, produced by a signal generator, causes |
| Colpitts Oscillator A Colpitts oscillator, invented in 1920 by American engineer Edwin H. Colpitts, is one of a number of designs for electronic oscillator circuits using the combination of an one inductance (L) with two capacitor (C1,C2) for frequency determination. |
| Hartley Oscillator Hartley Oscillator is an electronic oscillator,which uses two inductor and a capacitor to determine frequency.It is high frequency generator.Invented in 1915 by American engineer Ralph Hartley. |
