This experiment demonstrates the use of two transistors in an astable multivibrator circuit to generate a square wave signal.
1. Connect the two transistors in a cross-coupled configuration, with each transistor's collector connected to the base of the other.
2. Add capacitors and resistors to form the timing components for the oscillation.
3. Power the circuit and measure the frequency of the output square wave signal.
You will get a square wave signal with a frequency determined by the resistor and capacitor values.
