title: [Signal analysis of the ultrasonic study and recording system].
abstract: Signal processing of ultrasound has advanced from the analog system to the digital system, which provides improved images. Digital scan converter is one of the new advances and the recently developed full digital system is another. The recording system has also evolved. These techniques will contribute to the evolution of ultrasonic images.
