Low Pass Filter Calculator is a specialized tool designed to help engineers, students, and hobbyists calculate the critical parameters of a low pass filter circuit. This type of filter allows signals with frequencies below a certain cutoff point to pass through while attenuating higher frequencies. The calculator simplifies the process of determining key values such as cutoff frequency, resistor and capacitor values, and time constants.

Usage Guidance: To use the Low Pass Filter Calculator, input the known values (e.g., resistor or capacitor values) into the designated fields. The calculator will automatically compute the missing parameters based on the standard low pass filter formula:

• Cutoff Frequency (fc): The frequency at which the signal is attenuated by 3 dB.
• Resistor (R): The resistance value in ohms (Ω).
• Capacitor (C): The capacitance value in farads (F).
• Time Constant (τ): The product of R and C, representing the filter's response time.

Example: If you input a resistor value of 1kΩ (1000 Ω) and a capacitor value of 1μF (0.000001 F), the calculator will compute the cutoff frequency as approximately 159.15 Hz and the time constant as 0.001 seconds.

This calculator is particularly useful for designing audio systems, signal processing circuits, and noise reduction applications. Ensure all input values are in consistent units (e.g., ohms and farads) for accurate results.
