ST, EMP extend partnership for baseband project

What is baseband?
In signal processing, baseband describes signals and systems whose range of frequencies is measured from zero to a maximum bandwidth or highest signal frequency. It is sometimes used as a noun for a band of frequencies starting at zero.
In telecommunications, it is the frequency range occupied by a message signal prior to modulation.
It can be considered as a synonym to low-pass.
Baseband is also sometimes used as a general term for part of the physical components of a wireless communications product. Typically, it includes the control circuitry (microprocessor), the power supply, and amplifiers.
A baseband processor is an IC that is mainly used in a mobile phone to process communication functions.

What does analogue mean?
A continuously varying signal. For example, if an analogue signal's range is from 0V to 5V, the signal can assume any voltage within that range such as 1.2, 2.4, or 4.7V. Microprocessors and microcontrollers usually cannot process analogue signals directly and require conversion by an A/D converter before they can process the signal.
