Hi
my professor gave us a circuit to create as an assignment , he wants us just to learn the technical part before we gets into real science , so i don't understand how it works i just have the diagram.
i connected it on a bread board but it didn't do anything! just nothing i think there is an error in the values of resistors or maybe i got wrong transistors he didn't mention what model to use just npn or pnp so i got help from a pre-junior friend and told me about some models but i'm not sure if they are correct.
the circuit is supposed to amplify the sound produced from the mic , but i get nothing.
A second question , how would i simulate such circuit on multisim i can't find the transistor models which is pnp bc160 and npn c945 in its database also i can't find a speaker or a mic?
note:
mic is capacitor type (didn't find any other type at the shop)
resistances are 3Ohms and 2 Watts
diodes are pn junctions up to one ampere
speaker is of 8 ohms and 0.5 watts of power
Thanks
