Recovering audio from a modulated wave.

| Issue | Solution | |-------|----------| | | Download MC1496.LIB from onsemi.com and use SPICE Model Compiler in Proteus (Tools → SPICE Model Compiler). | | Convergence errors | Add 1kΩ resistors from each input to GND. Set GMIN=1e-9 in Simulation Settings. | | Distorted output at high frequency (>5 MHz) | Use a discrete BJT model (e.g., build with 2N3904 array) for RF simulations. | | DC offset at output | Insert 100 µF capacitors in series with outputs or use a balanced load. | | Incorrect pin mapping | Compare with datasheet. Some user-created symbols swap pins 5/6 or 7/8. |
