I am an electrical engineer, my first question is that how electric signals move inside wires? how to initiate the electrical signals knowing that in order for the electron to move in a circuit, we need a continuous voltage which is not the case in the signals.
my second question is that in the basic logic gates in a typical computer, are the inputs of the gate always have a constant supply of current or voltage or they are only signals
thanks
