Tolong jelaskan mengenai Electronics dari Cutoff frequency dalam bahasa sunda

In electronics, cutoff frequency or corner frequency is the frequency either above which or below which the power output of a circuit, such as a line, amplifier, or electronic filter is  the power of the passband. Because power is proportional to the  square of voltage, the voltage signal is  of the passband voltage at the corner frequency. Hence, the corner frequency is also known as the −3 dB point because  is close to −3 decibels. A bandpass circuit has two corner frequencies; their geometric mean is called the center frequency.
