(a(i))[1]
Identify the component shown as block X.
(a(ii))[1]
Identify the component shown as block Y.
(a(iii))[1]
Identify the component shown as Z.
(b(i))[1]
State the least number of bits in each digital number so that the signal in Fig. 12.2 can be sampled fully. Each output number from the ADC is a digital number, and the smallest bit represents $1\,\text{mV}$.
(b(ii))[1]
State the digital number produced by the ADC at time $0.50\,\text{ms}$.
(c)[4]
The ADC samples the signal in Fig. 12.2 at a frequency of $4.0\,\text{kHz}$. The first sample is taken at time zero. Using data from Fig. 12.2, draw, on the axes of Fig. 12.3, the change with time of the output at point Q for time zero to time $1.5\,\text{ms}$.
