Question
fL = Lower cut off frequencyfH = Higher cut off frequencyGain at the fH is 15 dBWhat will be the gain (theoretical) at the central frequency?
Solution
The gain at the central frequency for a bandpass filter is typically the maximum gain, which is higher than the gain at the cut-off frequencies. However, in this case, you have only provided the gain at the higher cut-off frequency (fH), which is 15 dB.
Without additional information, such as the filter type or the gain at the lower cut-off frequency (fL), it's not possible to provide a specific theoretical gain at the central frequency.
In general, for a bandpass filter, the gain at the central frequency is usually the maximum gain. But again, without more specifics, it's not possible to provide a numerical value.
