continuous-time signal

If the energy of a continuous-time signal x(t) is E and the energy of the signal 2x(2t − 1) is cE, then c is ________ (rounded off to 1 decimal place).

If the energy of a continuous-time signal $x(t)$ is $E$ and the energy of the signal $2x(2t - 1)$ is $cE$, then $c$ is _____ (rounded off to 1 decimal place).

Consider the two continuous-time signals defined below: $x_1(t) = \begin{cases} |t|, & -1 \le t \le 1 \\ 0, & \text{otherwise} \end{cases}$, $x_2(t) = \begin{cases} 1-|t|, & -1 \le...

The signal energy of the continuous-time signal $x(t) = [(t-1)u(t-1)]-[(t-2)u(t-2)]-[(t-3)u(t-3)]+[(t-4)u(t-4)]$ is

Let f(t) be a continuous time signal and let F($$\omega$$) be its Fourier Transform defined by $$F\left(\omega\right)=\int_{-\infty}^\infty f\left(t\right)e^{-j\omega t}dt$$. Defin...
