The digital-to-analogue converter of Figure 10.6(a) is required to give an output voltage in the range 0 to 2.55 V, corresponding to an 8-bit digital input signal 00000000 to 11111111. (a) Assuming VREF = -15 V, R= 1 kN, calculate the value of Rp required. (b) Find the output voltage corresponding to an input signal of 11000101.
