Question

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.
