MCQ (Single Correct Answer)

-0.3

Two $$8$$ $$A$$ $$D$$ $$C$$ $$s$$ one of single slope integrating type and other of successive approximation type. Take $${T_A}$$ and $${T_B}$$ times to connect $$5V$$ analog input signal to equivalent digital output. If the input analog signal is reduced to $$2.5V$$ the approximate time taken by the two $$ADC's$$ will respectively be

$${T_A},\,\,{T_B}$$

$${\raise0.5ex\hbox{$\scriptstyle {{T_A}}$} \kern-0.1em/\kern-0.15em \lower0.25ex\hbox{$\scriptstyle 2$}},\,\,{T_B}$$

$${T_A},\,\,{\raise0.5ex\hbox{$\scriptstyle {{T_B}}$} \kern-0.1em/\kern-0.15em \lower0.25ex\hbox{$\scriptstyle 2$}}$$

$${\raise0.5ex\hbox{$\scriptstyle {{T_A}}$} \kern-0.1em/\kern-0.15em \lower0.25ex\hbox{$\scriptstyle 2$}},\,\,{\raise0.5ex\hbox{$\scriptstyle {{T_B}}$} \kern-0.1em/\kern-0.15em \lower0.25ex\hbox{$\scriptstyle 2$}}$$
