Question

a)There should be a half-line difference between odd and even fields in a TV system using interlaced scanning. How is this made possible in practice? b) In a certain country where the power supply frequency is 60 Hz the horizontal oscillator frequency of the monochrome TV system (with interlaced scanning )used was found to be 15.75 kHz. Calculate the no. of lines per frame, the vertical oscillator frequency and the no. of frames per sec. c) The following two frequencies (f1 and f2) are related to ionospheric sky wave propagation : f1 =27 MHz , f2 = 9 MHz. One of them is the maximum frequency returned by the ionosphere when the waves are transmitted vertically upwards, and the other is the maximum frequency returned by the ionosphere at zero take-off angle. (a) Name these two frequencies f1 and f12. (b) Also calculate the height of the F layer for these pair of frequencies. Assume that the radius of earth (R) is 6371 km.
