Two discrete time systems with impulse responses h1[n] = δ[n - 1] and h2[n] = δ[n - 2] are connected in cascade. The overall impulse response of the cascaded system is
Assuming zero initial condition, the response y(t) of the system given below to a unit step input u(t) is
\[\xrightarrow{{U\left( s \right)}}\boxed{\frac{1}{s}}\xrightarrow{{Y\left( s \right)}}\]
A 1.0 kHz signal is flat-top sampled at the rate of 1800 samples/sec and the samples are applied to an ideal rectangular LPF with cut-off frequency of 1100 Hz, then the output of the filter contains
The input and output of a continuous time system are respectively denoted by x(t) and y(t). Which of the following descriptions corresponds to a casual system?
The DFT of a vector [a b c d] is the vector [α β γ δ]. Consider the product
\[\left[ {p\,q\,r\,s} \right] = \left[ {a\,b\,c\,d} \right]\left[ {\begin{array}{*{20}{c}}
a&b&c&d \\
d&a&b&c \\
c&d&a&b \\
b&c&d&a
\end{array}} \right]\]
The DFT of the vector [p q r s] is a scaled version of
