The FM receiver is the whole unit which takes the modulated signal as input and outputs the original audio signal. Radio amateurs are the initial radio receivers. They had got drawbacks such as poor sensitivity and selectivity.Selectivity is the selection of a particular signal while rejecting the others. Sensitivity is the capacity of detecting RF signal and demodulating it, while at the lowest power level. Both Selectivity and Sensitivity should be high for an FM receiver. To overcome these drawbacks of the ordinary receiver, the superheterodyne receiver was invented. This FM receiver consists of 5 main stages.RF Tuner SectionThe modulated ... Read More

To improve the radiation efficiency and directivity of the beam, the waveguide should be provided with an extended aperture so as to make the abrupt discontinuity of the wave into a gradual transformation, so that all the energy in the forward direction gets radiated. This can be termed as Flaring. Flaring is done to provide greater directivity and narrower beam width. The types of horn antennas depend on how they are flared.Sectoral HornThis type of horn antenna, flares out in only in one direction. Flaring in the direction of Electric vector produces the sectorial E-plane horn. As well, flaring in ... Read More
