Determine the output of the DAC in Figure (a) if the waveforms representing a sequence of 4-bit numbers in Figure (b) are applied to the inputs. Input DO is the least significant bit (LSB). 200 k Do o W 23 45 6789 1011 12 1314 15 100 k) +5 V 10 k Do +5 V D +5 V D, o 50 kfl D; o M D2 +5 V 25 kfl D, o W (a) (b)

A 4bit D/A converter use an inverting summer as its output stage. The input voltages can be either 0 or 5 V in a binary sequence. The input resistors are as follows: R1 = 1 k, R2 = 2 k, R3 = 4 k, R4 = 8 k, and RF = 1 k. Determine the output voltage for the case where the V1 = 5 V, V2 = 5 V, V3 = 0 V, and V4 = 5 V.
