Question

The frequency response $H\left( \Omega \right)$ of a system for impulse sequence response$h\left[ n \right] = \delta \left[ n \right] + \delta \left[ {n - 1} \right]$ is

TuteeHUB · Accepted Answer

$H\left[ \Omega \right] = \cos \Omega \angle - \Omega$

TuteeHUB · Answer

$H\left[ \Omega \right] = 2\cos \left( {\frac{\Omega }{2}} \right)\angle - \frac{\Omega }{2}$

TuteeHUB · Answer

$H\left[ \Omega \right] = 2\cos \Omega \angle - \frac{\Omega }{2}$

TuteeHUB · Answer

$H\left[ \Omega \right] = 2\angle - \frac{\Omega }{2}$

1.	The frequency response \(H\left( \Omega \right)\) of a system for impulse sequence response\(h\left[ n \right] = \delta \left[ n \right] + \delta \left[ {n - 1} \right]\) is
A.	\(H\left[ \Omega \right] = 2\cos \left( {\frac{\Omega }{2}} \right)\angle - \frac{\Omega }{2}\)
B.	\(H\left[ \Omega \right] = \cos \Omega \angle - \Omega\)
C.	\(H\left[ \Omega \right] = 2\cos \Omega \angle - \frac{\Omega }{2}\)
D.	\(H\left[ \Omega \right] = 2\angle - \frac{\Omega }{2}\)
Answer» B. \(H\left[ \Omega \right] = \cos \Omega \angle - \Omega\)

The frequency response \(H\left( \Omega \right)\) of a system for impulse sequence response\(h\left[ n \right] = \delta \left[ n \right] + \delta \left[ {n - 1} \right]\) is
