SUMMARY
The discussion focuses on calculating the cut-off frequency for a Low Pass Filter using two operational amplifiers (op-amps). The formula provided is fc = 1/(2∏(fn)RC), where fn represents the frequency response of each op-amp, and R and C are the resistance and capacitance values, respectively. Participants clarify that each op-amp's parameters should be calculated separately, and then the results can be combined to determine the overall cut-off frequency of the filter. A circuit diagram is suggested for better visualization of the setup.
