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

Two Sinusoidal signal $$p\left( {{\omega _1}t} \right) = A\,\sin \omega t,$$ and $$q\left( {{\omega _2}t} \right)$$ are applied to $$X$$ and $$Y$$ inputs of a dual channel $$C.R.O,$$ the lissajous figure displayed on the screen is shown below. The signal $$q\left( {{\omega _2}t} \right)$$ will be represented as

The ac bridge shown in the figure is used to measure the impedance $$Z.$$ If the bridge is balanced for oscillator frequency $$f=2$$ $$kHz$$, then the impedance $$Z$$ will be

A bridge circuit is shown in the figure below. Which one of the sequence given below is most suitable for balancing the bridge?
