GATE ECE 2008 | Question: 83
In the following circuit, the comparator output is logic $\text{ 1 }$ if $\mathrm{V}_{1}>\mathrm{V}_{2}$ and is logic $\text{ 0 }$ otherwise. The D/A conversion is done as per the relation $V_{\mathrm{DAC}}=\displaystyle{}\sum_{n=0}^{3} 2^{n-1} b_{n}$ ... magnitude of the error between $V_{D A C}$ and $V_{i n}$ at steady state in volts is $0.2$ $0.3$ $0.5$ $1.0$

The impulse response $h(t)$ of a linear time-invariant continuous time system is given by $h(t)=\exp (-2 t) u(t)$, where $u(t)$ denotes the unit step function. The output of this system, to the sinusoidal input $x(t)=2 \cos (2 t)$ for all time $t,$ is $0$ $2^{-0.25} \cos (2 t-0.125 \pi)$ $2^{-0.5} \cos (2 t-0.125 \pi)$ $2^{-0.5} \cos (2 t-0.25 \pi)$
