Webเมื่อ Z S หมายถึงอิมพีแดนซ์ลักษณะเฉพาะ (อังกฤษ: characteristic impedance) (หรือแค่อิมพีแดนซ์) ของสายส่ง, การสะท้อนต่ำสุดจะเป็นไปได้เมื่อ The characteristic impedance or surge impedance (usually written Z0) of a uniform transmission line is the ratio of the amplitudes of voltage and current of a single wave propagating along the line; that is, a wave travelling in one direction in the absence of reflections in the other direction. Alternatively, and equivalently, it can be defined as the input impedance of a transmission line when its length …

WebIn digital circuits, a high impedance (also known as hi-Z, tri-stated, or floating) output is not being driven to any defined logic level by the output circuit. The signal is neither driven to a logical high nor low level; this third condition leads to the description "tri-stated". [1] Such a signal can be seen as an open circuit (or "floating ...
