Bell Labs Wave Machine: Matched Impedence

Three segments of the Bell Labs Wave Machine are connected together. The points at which they are connected have the same impedance. Therefore, traveling waves will not be reflected at these boundaries. One can also observe the change in wavelength and velocity as waves travel from high im

Bell Labes Wave Machine: Mismatched Impedence

Two segments of the Bell Labs apparatus are connected. The segments have different impedance. When a pulse travels from high impedance to low impedance, it is reflected with positive polarity and transmitted with positive polarity. When a pulse travels from low impedance to high impedance,
