A signal transduction pathway is a group of proteins that carry out transducing signals (which means it converts signals from outside the cell to a different signal inside the cell). A good example...
i think analog signal is that signal where your signal strength changes everytime and in digital signal your signal strength is stedy. Analog signal has a varying numerical value while digital has...
A signal x(t) is called an energy signal , if the energy is finite and the power is zero. A signal x(t) is called an power signal , if the power is finite and the energy is infinite.
