Dear all, I’m currently learning basic electronics and following Make Electronics, Third Edition by Charles Platt. I am trying to create this circuit in Multisim, but I’m finding it quite challenging. I would appreciate any help with the following questions: How do I connect the speaker with the 100-ohm resistor? When I run the simulation for a few seconds, it doesn’t produce any sound. I think the speaker might need to be connected differently, but I’m unsure how. ( Image 11_10_No_Sound ) How can I calculate the pulses generated by the circuit? In the screenshot “11_10_oscilloscope,” I don’t see the capacitors charging and discharging. I’m not sure what needs to be adjusted. ( Image 11_10_Oscilloscope ) If anyone could create a working version of this circuit, it would really help me identify my mistakes and understand the setup better. ( Image 11_10_circuit_sound_astable ) Thank you very much for your support. Best regards

Help Needed: Troubleshooting Speaker Connection and Pulse Calculation in Multisim Circuit

Dear all,

I’m currently learning basic electronics and following Make Electronics, Third Edition by Charles Platt. I am trying to create this circuit in Multisim, but I’m finding it quite challenging.

I would appreciate any help with the following questions:

How can I calculate the pulses generated by the circuit?
