• What is the transfer function of a low-pass filter?

  Low Pass Filters and their Transfer Functions
  As its name implies, a low pass filter is an electronic device that allows low frequency AC signals to pass a current through the filter circuit. The output from the filter circuit will be attenuated, depending on the frequency of the input signal.

• What is LPF vs HPF transfer function?

  LPF circuit allows the frequency underneath cut-off frequency for flowing through it. HPF circuit allows the frequencies over cut-off frequency for flowing through it. It can be built with a resistor which is followed by a capacitor. It can be built with a capacitor which is followed by a resistor.

• What is the transfer function of filter?

  The transfer function of a filter is the Z-transform of its impulse response. For an FIR filter, the Z-transform of the output y, Y(z), is the product of the transfer function and X(z), the Z-transform of the input x: Y ( z ) = H ( z ) X ( z ) = ( h ( 1 ) + h ( 2 ) z ? 1 + ? + h ( n + 1 ) z ? n ) X ( z ) .
• A low-pass filter's cutoff frequency, f_c, is the frequency at which the filter's gain is ?3dB. Frequencies lower than the cutoff frequency are admitted through the filter, and higher frequencies are blocked. For the typical RC low-pass filter, f_c = 1 / (2?RC).
