In radar systems, PRF stands for:

What is the nature of the independent variable in real-valued and complex-valued functions?

What is the other name of a Continuous Time Unit Impulse Function?

In low-pass signal flat-top sampling,

If the Z Transform of u_n is U(z) and the Z Transform of v_n is V(z), what is the value of Z{au_n + bv_n}?

Consider an 8-point DFT of a real sequence where the first 6 points are given as: -4, 2 - j4, 0, 4 - j3, 0, 4 + j3. Find the last two points.

Two systems with impulse responses h1[n] = δ[n-3] and h2[n] = δ[n-1] are connected in cascade. Find the overall impulse response of the cascaded system.

A CDMA system consists of 15 equal power users that transmit information at a rate of 10 kbps, each using a DS spread spectrum signal operating at a chip rate of 1 MHz. The modulation scheme is BPSK. The value of εb/J0 is

A direct sequence spread binary phase-shift-keying system uses a feedback shift register of length 19 for the generation of PN sequence. The system is required to have an average probability of symbol error due to externally generated interfering signals that does not exceed 10^-5. The processing gain of the system is
