High pass active filter by LM741
The high pass filter circuit is a high frequency filter, only through it. In this circuit we are use operational amplifiers IC 741 number, it is allows this circuit has a lot performance,and has cut off frequency precise. Despite the possibility of multi-circuit filter,With different levels of growth and differentiation of a roll back in the op-amp IC. But this circuit can reduce the frequency cut off, so successful, the device configuration, R1 = R2, C1 = C2.
