SECOND ORDER LOW PASS FILTER APPLICATION CIRCUIT
The Second Order Low Pass Filter application circuit only needs very few components. The Cross-Over Filter
Point can be adjusted by modifying the values of capacitors -- C1, and C2. For better circuit characteristic, it is
recommended that C2 be twice the value of C1. Please refer to the diagram below.
