Difficult part was in the two video conference with french people as their english pronunciation is not very good.
1) Given a filter transfer function, would the filter coefficients be real or imaginary. 2) Explain the process of BPSK and QPSK modulation, their constellation diagrams and how incoming bits are mapped to waveforms. 3) What would happen if there was a frequency error in these modulation schemes, and the effect that would have on the constellation diagram. [The frequency errors would cause the constellation diagram to rotate around the origin point with a angular rate determined by the frequency shift] 4) Since execution time on a processor is valuable, what is the best way to compute the number of 1s in the binary representation of a given number? Write a pseudo code for the same. [The logic he was expecting is monitor the LSB for 1 or a 0, right shift the number by 1, check the LSB and so on.] 5) If a device has the following response on a Smith Chart, how would you match it? 6) What are the different antenna measurement ranges? How does a compact antenna range work? 7) Question related to two-port network theory and properties of S-matrix, specifically unitary properties.
