Nerve impulses.
When several signal transmitted simultaneously. this is called multiplexing of signals.many signal are combined into one and then they transmitted.
The range of frequencies that can be transmitted is called the bandwidth. It refers to the range of frequencies within a signal that can be effectively transmitted through a communication channel.
it is first converted into an electric signal by your telephone, and then transmitted over the copper wire
the digital signal is converted to analog signal after using by transmitted antenna
When you pluck a string, the guitar pickup creates a signal by capturing the change in magnetic field. This signal is transmitted to the amplifier via a patch cord.
The device that converts sound into an electrical signal is called a microphone. It captures sound waves and converts them into an electrical signal that can be amplified, recorded, or transmitted.
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
In the human brain, a signal is transmitted from one neuron to another through a process called synaptic transmission. When an electrical signal, known as an action potential, reaches the end of a neuron, it triggers the release of chemical messengers called neurotransmitters into the synapse, the gap between neurons. These neurotransmitters then bind to receptors on the receiving neuron, causing a new electrical signal to be generated and continue the communication between neurons.
the signal goes out of sink due to refraction
