Which bitmap file format/s support/s the Run Length Encoding (RLE)? A discrete time, which is both linear and time invariant, the impulse response is u[n]. What is the response of the system for an input δ[n - 4]? A bandlimited signal is sampled at the Nyquist rate. The signal can be recovered by passing the samples through Dispersion in an optical fibre used in a communication link is of which type? Match List-I with List-II and select the correct answer using the options given below: List-I (Function) List-II (Fourier Transforms) a. $$\exp \left( { - \alpha t} \right)u\left( t \right),\,\alpha > 0$$ 1. $$\frac{1}{{{{\left( {\alpha + j2\pi f} \right)}^2}}}$$ b. $$\exp \left( { - \alpha \left| t \right|} \right),\,\alpha > 0$$ 2. $$\frac{1}{{\alpha + j2\pi f}}$$ c. $${\text{texp}}\left( { - \alpha t} \right)u\left( t \right),\,\alpha > 0$$ 3. $$\delta \left( {f - \frac{\alpha }{{{t_0}}}} \right)$$ d. $$\exp \left( {j2\pi \alpha t/{t_0}} \right)$$ 4. $$\frac{{2\alpha }}{{{\alpha ^2} + {{\left( {2\pi f} \right)}^2}}}$$
