TIFR System Science 2018 Question 1
Consider a discrete-time system which in response to input sequence x[n] (n integer) outputs the sequence y[n] such that $y[n] = 0, n = −1, −2, −3,...$ and $y[n]=2 (y[n − 1] + nx[n]), n = 0, 1, 2,...$. Find out if the system is linear and time-invariant.

NIELIT 2017 OCT Scientific Assistant A (CS) - Section D: 8
A carrier $Ac\cos(\omega c)t$ is frequency modulated by a signal $Em\cos(\omega m)t.$ The modulation index is $mf.$ The expression for the resulting FM signal is $Ac\cos [\omega ct + mf\sin(\omega m)t]$ ... $Ac\cos [\omega ct + 2\pi mf Em \cos(\omega m)t/\omega m]$
