Sounds like the head light switch went bad or a lose wire. If you drive for a long time with the lights on the plastic on the switch will melt making the pins lose. Another thing to check are the fuses. It could just be a ground some where. But I would start at the switch
The analog method of signal transmission uses radio waves to carry signals. Digital transmission involves the use of satellites to transmit signals.
They can be interfered by other transmission signals
satellite signals
Primary transmission refers to public transmission using signals that are also forwarded for secondary transmission irrespective of location.
vacuum tubes
The most common mode of transmission of TV signals are digital satellite and cable. New technologies allow transmission of signals by digital terrestrial TV, using aerial broadcasts to a conventional antenna. This provides a greater number of channels and a better picture and sound quality.
it is baseband transmission
noise
Signal attenuation along a transmission route The amplification that signals require along a transmission route to maintain their strength
the part that facilitates the the transmission of signals is collectively known as the axon but more peculiarly known as the nerve endings.
They can be trasmitted
A form of transmission that allows multiple signals to travel simultaneously over one medium is known as multiplexing
