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.
Describe the technique of analogue to digital conversion by means of "successive approximation". Base your discussion around generating a 7-bit PCM (pulse code modulation) codeword for the case where the system accommodates input voltages in the range starting from 0 V up to approximately 1 V. Provide an example of converting 0.86 V to its counterpart 7- bit PCM codeword.
Suppose the input signal is 7.3 V. If using the successive approximation method to encode the signal for a 6-bit register for an ADC with a full-scale range of 13 V, the value in decimal number will be: (Fill in the blank) my steps: 2^7=128 13/128 =0.101 (7.3/13)*128= 71.876 (which is incorrect)

An 10-bit analog-to-digital converter (ADC) has a voltage range of 0 to 12 V and a digitization uncertainty of ±1 LSB. What is the maximum uncertainty if the digitization is for a 12 V signal? What is the maximum uncertainty for a 18-bit ADC, and for 43-bit?
