Use Proteus program to construct the circuit that implements an Analog-to-Digital Converter (ADC). This circuit takes an analog signal and gives a digital thermometer code. Vary the input voltage. Record the values of the input voltage when each LED switches on. +15V 12k Ving ZVn4 www Vn1 V63 1KO Vn2 1k0 4700 Led1 5 +must IKO Vol IkQ 1KQ Vo2 1KQ Led2 5 1K0 Vo3 1KO Led3 www 1K0 V04 1K0 Led4 2. Assume that the voltages in the circuit of Fig. 1.5(a) can be either 0 or 5V. Build the circuit in Proteus. Change the combination of V.V,V, as shown in the table and record the output voltages.
