Ultrasonic Transducers

Report
Design a compact driver board for piezoelectric ultrasonic transducers to saturate MEMS microphones in near-field operation. The system must use 18–30 kHz variable frequency and multiharmonic PRN modulation to create a broadband spectrum with no filtering above 30 kHz.
