If you are analyzing it in terms of voltage ratio then attenuation c… The amount of attenuation that occurs will depend on the type of tissue the sound wave is traveling through. ATTENUATION As the ultrasound beam travels through the body it loses energy. Attenuation is caused by signal absorption, connector loss, and coupling loss. See more. If your terminations are properly done and equal then the ratio of the output to input power or voltage is called attenuation. A wide area network (WAN) is a large network of not tied to a single location. Repeaters take in the signal being sent, process it and then send out the signal stronger than before to the next waypoint (either Hot temperatures can cause signals to overheat, potentially even catching fire if the outside plastic melts away and the inside wire is exposed to flammable materials. check_circle Expert Answer. However, amplification can also affect the noise in the transmission, potentially degrading the quality of the signal. LANs can connect to form wide area networks (WANs). Antennas typically work well with, or are required for, booster equipment. Copper cables, although cheap and common, can be less effective and may experience attenuation more frequently that other types of cables. Attenuation artifacts vary among patients, but the most common corrections are to artifacts associated with breast attenuation in women and diaphragmatic attenuation in men. In other words, it is the gradual extinction of the energy through the transmission medium or a ratio that compares input power to output. This is known as attenuation. Attenuation is the loss of signal strength in networking cables or connections. For example, using shorter cables, or moving the end product closer to the signal source, can also help improve signal strength. However, signal attenuation can be prevented or improved with some easy adjustments. Attenuation is a reduction or loss of intensity or energy.
