Cause: The library you downloaded only contains the graphical schematic layout, not the underlying SPICE simulation model.
A: Absolutely. In simulation, inject BFO signal to carrier input and SSB to audio input.
Official Proteus libraries typically do not include the MC1496. You can source it from these platforms: mc1496 proteus library download
Connect an Oscilloscope to the output and run the simulation. You should observe a suppressed carrier modulated signal. Troubleshooting Library Issues
Navigate to the DATA\LIBRARY or LIBRARY folder. Common paths include: Cause: The library you downloaded only contains the
High-frequency carrier signals causing mathematical convergence failures in VSM.
The MC1496 relies on specific biasing configurations. Ensure Pin 5 has a proper current-limiting resistor attached to the negative rail, or the simulated internal transistors will remain in a cut-off state. Official Proteus libraries typically do not include the
Using a single 5V or 12V supply, as some hobbyists attempt, will often result in improper biasing and no output signal. One user discovered that a single 12V supply worked in simulation but failed on a physical breadboard, indicating that dual supplies are essential.
