1) pulse length or damping (The amount of time the pulse is applied to the transducer)
2) pulse energy (The voltage applied to the transducer. Typical pulser circuits will apply from 100 volts 800volts to a transducer) in the receiver section the voltage signals produced by the transducer, which represent the received ultrasonic pulses, are amplified. The amplified radio frequency (RF) signal is available as an output for display or capture for signal processing. Control functions associated with the receiver circuit include.
3) signal rectification ( The RF signal can be viewed as positive half wave, negative half wave or full wave
4) Filtering to shape and smooth return signals.
5) Gain, or signal amplification.
6) Reject control.
The pulser - Receiver is also used in material characterization work involving sound velocity or attenuation measurements, which can be correlated to material properties such as elastic modulus. In conjunction with a Stepless gate and a spectrum analyzer, pulser - Receivers are also used to study frequency dependent material properties or to characterize the performance of ultrasonic transducers.
