Ultrasound technology is limited due to the power requirements of an input signal that will resolve in a bandwidth sufficient for clear images. The enlarged power requirements poses a serious problem for portable implementation. There is a need to reduce the power of the input signal so that ultrasound can be useful in long-term battery operated devices, such as prosthetics that require a long-term imaging solution.

One of the concepts that we will use in our project is time delay spectrometry (TDS). It was first invented by Dr. Richard Heyser in 1967. Its main purpose is for acoustics in sound systems such as loudspeakers and sonar.  It allows for measurement of the time associated with absorption at various frequencies. It reduces the amount of data for processing by eliminating frequency responses out of the realm of application importance. This could result in better image resolution than other ultrasound signaling techniques.

With this in mind,  the overall objective is to design a new way to process signals using Time Delay Spectroscopy that will reduce power constraints and contribute to future efforts for a portable transducer cuff technology used in prosthetics motor control.

For our project, we will recreate this system. However, in our system we want to see the response of the system using TDS and complex media.
