1.	In which of the following the nulls are introduced effectively when different other users interferes the desired user?(a) Adaptive array(b) Switching beam(c) Phased array(d) Sub-arrayI have been asked this question during a job interview.My question comes from Adaptive Array in section Phased, Adaptive and Binomial Arrays of Antennas
Answer» RIGHT answer is (a) Adaptive ARRAY To explain I would say: The advanced digital signal processing in the adaptive arrays helps to reduce the interference compared to switch BEAMS. These adaptive arrays detect the noise interference and also used to suppress it in desired direction. PHASED array and sub array don’t PROVIDE this.
