A constant input analogue voltage of 5.2V is input to a 4-bit successive approximation ADC. The ADC has an input range of 0-16V, the maximum binary output possible being 1111 – for any input voltage greater than 15V. List and explain the sequence of interim approximations that will be output by the register/DAC and the converter’s final output.
