Webtraditional MTF – namely the requirement for sinusoidal input target and the lack of exposure control. Two modifications to MTF are done. This new method will be referred to as CTF … WebCTF, at any frequency can be expressed as a summation of harmonic components. These components are weighted by two multiplicative factors in the summation: their relative strength in the input waveform and the MTF of the system under test at each harmonic frequency. This process yields an expression3 for CTF in terms of MTF (4) slytherin badge
