    • A system for directly displaying steady state waves, such as sound waves, ultrasonic waves, electromagnetic waves, and the like, by instantaneously sampling the amplitude of the waves in a known phase relationship with some other portion of the wave train. The system includes a source of the waves, such as a speaker, and a transducer, such as a microphone, an electrical signal source being coupled to the wave signal source, and the transducer being connected to a sample and hold circuit whose output is applied to a light emitting diode (LED), or other display unit. The transducer is moved towards and away from the wave signal source in the path of the waves eminating from the wave signal source. In the following description the system will be described in conjunction with wound waves traveling in air, eminating from a speaker and transduced by a microphone. It will be evident as the description proceeds that the system may be used for displaying waves other than sound waves, such as ultrasonic waves; and/or for displaying waves traveling in a medium other than air.
    • 通过以波束的一些其他部分以已知的相位关系瞬时采样波的振幅,直接显示声波,超声波,电磁波等稳态波的系统。 该系统包括波源,例如扬声器和诸如麦克风的换能器,耦合到波信号源的电信号源,并且换能器连接到其输出被施加的采样和保持电路 发光二极管(LED)或其他显示单元。 在从波信号源发出的波的路径中,换能器朝向和远离波信号源移动。 在下面的描述中,系统将结合在空气中传播的伤口波来描述,从扬声器排出并由麦克风转换。 随着描述进行,系统可以用于显示声波以外的波,例如超声波; 和/或用于显示在除空气以外的介质中行进的波。
