The amplitude and phase (in radians) of the three components of the TF10 model of the time response. The solid red line is Hbolo(f), the dotted green line shows Hfilter(f) and the dashed blue line shows Hres. The solid black line is H10(f), the product of the three components. The vertical dotted black line shows the signal frequency where the beam of a 217 GHz channel cuts the signal power by half.
