An Investigation for Miniaturized, Light-Weight and High-Power Tonpilz Piezoelectric Transducers

Method and apparatus for converting an analog pulse-width signal into a digital signal through the transmission of the analog signal through a delay loop. The resulting delayed signal is then combined with the original signal in an OR gate providing an output of the combined signals. If the width of the original signal is greater than the delay loop a bit 1 is output for the digital signal and the resulting signal from the OR gate is transmitted to the next stage. If the width of the analog signal is less than or equal to the delay loop a bit of 0 is transmitted as the digital signal and the delayed signal is transmitted to the next stage unchanged.
