Speed Longevity purpose What carries the signal Where the signal is transmitted received
The sound signal must firstly be changed into an electrical signal.
A base signal that is modulated with the information being transmitted.
They bring a conformational change to each protein.
neuronal cell signals travel throughout the body through the nervous system. The signal is electrical, and the fastest type of cellular signal. The electrical impluse is generated by action potentials.
Nerve impulses.
When several signal transmitted simultaneously. this is called multiplexing of signals.many signal are combined into one and then they transmitted.
the digital signal is converted to analog signal after using by transmitted antenna
Analog signals are transmitted as electrical waves.
Reflection of a transmitted signal is the basic premise of radar and sonar.
Yes, this is a true statement. A TV channel is most often characterized by the frequency of its transmitted signal.
Radio Waves
the signal goes out of sink due to refraction
First of all digital signal cant be transmitted wirelessly. digital signal can only be transmitted through optical fibre in the form of pulses. so we have to convert digital signal to analog form with the help of DIGITAL TO ANALOG CONVERTOR ( D TO A CONVERTOR). Then this analog signal should be super imposed on carrier signal called MODULATION. modem can be used for that. then that signal can be transmitted to the air through alloted band width like cellular system with the help of transceiver. at the reciveing end we can demodulate the signal with the help of modem & can convert it back to digital form through A TO D CONVERTOR.
by analog to digital,digital to analog signal
Speed Longevity purpose What carries the signal Where the signal is transmitted received
Data modulation is a method of Electronic packing of data. In Data communication data is transmitted through a process which is called "Data Modulation".
