Let $f(t)$ be continuous time signal and let $F(w)$be its Fourier Transform defined by $F(\omega )=\int_{\infty }^{\infty }f(t)e^{jwt} dt$ define $g(t)$ by $g(t)=\int_{\infty }^{\infty }f(u)e^{jut} dt$ What is the relationship between $f(t)$ ... function. $g(t)$ would be proportional to $f(t)$ only if $f(t)$ is a sinusoidal function. $g(t)$ would never be proportional to $f(t)$.

The function shown in the figure can be represented as $u(t)u(tT)+\frac{(tT)}{T}u(tT)\frac{(t2T)}{T}u(t2T)$ $u(t)+\frac{t}{T}u(tT)\frac{t}{T}u(t2T)$ $u(t)u(tT)+\frac{(tT)}{T}u(t)\frac{(t2T)}{T}u(t)$ $u(t)+\frac{(tT)}{T}u(tT)2\frac{(t2T)}{T}u(t2T)$

Let the probability density function of a random variable, $X$, be given as: $f_{x}(x)=\frac{3}{2}e^{3x}u(x)+ae^{4x}u(x)$ where u(x) is the unit step function. Then the value of 'a' and prob $\left\{X \leq 0\right\}$, respectively are $2, \frac{1}{2}$ $4, \frac{1}{2}$ $2, \frac{1}{4}$ $4, \frac{1}{4}$
