We evolved a 2-bit DAC design to control our servomotors. What originates as a 2 bit control word must be converted to left, center & right as per the truth table mentioned below. The DAC O/P would be either 3.5, 5 or 6.5V. This analog voltage is given as input to a 555 timer circuit that produces the corresponding PCM control signal for the servomotors.
