Discussion reply: low pass filter

 A low pass filter can be defined as low frequencies that exist above a  cutoff frequency that will be permitted through a filter. A high-pass  filter operates below the cutoff frequency permitting higher frequencies  to pass through the filter. Low-pass filters are used to smooth out an  image, and they can help remove the aliasing effect. A high pass filter  can be used to sharpen an image and work to remove noise. The BJT  amplifier can act as a filter based on the quantity being amplified by  the circuit, so it could be power, voltage, or current being amplified. 

An  internal capacitor works to form a low-pass filter that has external  resistors. The external capacitance with a low frequency has a high  impedance making the gain low, and when high, there is a low impedance  and high gain. When it is a high frequency, the coupling with the bypass  capacitor is a short circuit and cannot affect the response of the  amplifier.

Having two cutoff frequencies will cause the higher to decrease and the lower frequencies to increase. 

When  multi-stage amplifiers are determined, the bandwidth can be determined  by the more stages there are, the steeper the high and low pass filters  will be. If and when the stages are capacitively coupled, then each  capacitor will roll off the chosen frequency.
