WebThe Channel Transfer Function (CTF) is first thoroughly investigated. The channel time-frequency characteristics are studied from a measurement campaign covering a frequency band up to 100 MHz. Different approaches for the modelling of the CTF are proposed. The contrast transfer function (CTF) mathematically describes how aberrations in a transmission electron microscope (TEM) modify the image of a sample. This contrast transfer function (CTF) sets the resolution of high-resolution transmission electron microscopy (HRTEM), also known as phase contrast TEM. By considering the recorded image as a CTF-degraded true object, describin… WebLTI channel’s output is a temporal-smeared version of the transmitted signal, but again, the CIR is time-invariant. In this case, a one-dimensional (1D) CIR in the delay domain h(˝) is sufficient for characterizing the time-dispersive channel. The Fourier transform (FT) of this CIR is a frequency-selective channel transfer function (CTF). button graphic red
