1. Radio Corporation of America(RCA) proposed to define resolution by three parameters, effective amplitude response,asymmetry postulate and MTF index, with measuring the shape of resolution aperture of pick up tube.
2. This chart consists of sloped fringes to find MTF index ‘K’ and sloped fringes to find resolution aperture.
The sloped fringes to find MTF index ‘K’ are equivalent to fringes of 28 to 1500TV MTF.
