Echocardiography, also known as cardiac ultrasound, is the use of ultrasound to examine the heart. It is a type of medical imaging, using standard ultrasound or Doppler ultrasound. [1] The visual image formed using this technique is called an echocardiogram, a cardiac echo, or simply an echo . Echocardiography is routinely used in the diagnosis ...
Echo cancellation and suppression can work in conjunction to achieve acceptable performance. Quantifying echo[edit] Echo is measured as echo return loss(ERL). This is the ratio, expressed in decibels, of the original signal and its echo.[8] High values mean the echo is very weak, while low values mean the echo is very strong.
