answer
1, the circuit function is different. A filter is composed of inductive capacitors or resistive capacitors to suppress or filter AC waves of a certain frequency. A chip is a high-density collection of microelectronics that performs a certain function.
2, the components are different. Filters generally consist of a network of resistors, capacitors, and inductors. A chip is a collection of high-density circuits with a certain function made by a special process on a silicon semiconductor substrate.
