In this hands-on semiconductor electronics experiment, build an astable multivibrator (oscillator) circuit that provides an output in the audio frequency range and learn the effect of component values and supply voltage on oscillation frequency.
Textbook
A circuit with an inductor (L) and capacitor (C) connected in parallel or series will have a resonant frequency at which their impedances are equal. Given two of the three values—inductance, capacitance, or resonant frequency—this tool will calculate the missing third variable.
