The block frequency reducing circuit of capacitors (wide band reaction signal regulator 1B31)
The block frequency reducing circuit of capacitors (wide band reaction signal regulator 1B31)
By the external capacitors CSEL1 and CSEL2, the block frequency of the low-pass filter can be set under 1KHz, which can meet the narrow band need, see as the figure. The capacitance computing formula is as follows.
