The bandwidth of impulse signal is infinity.because upper frequency is infinity.
it can not be both!
Instantaneous sampling is one method used for sampling a continuous time signal into discrete time signal. This method is called as ideal or impulse sampling. In this method, we multiply a impulse function with the continuous time signal to be sampled. The output is instantaneously sampled signal.
It is the traveling of the electrical signal down the length of a neuron.
If a neuron is not sending out an impulse or signal, this means the neuron is at rest. Neurons send signals electrochemically.
Nervous impulse is much quicker. Occurring almost instantly. Where as a hormone signal is a little more delayed. (changing of a males voice during puberty as an example)
The impulse response of an R-L circuit is an exponentially decaying signal. It represents the behavior of the circuit when subjected to a Dirac delta function input or an impulse signal. The response decays over time due to the inductor's energy storage capability.
The impulse must go from one neuron to the next. To do this, it must change from an electrical to a chemical signal, and back to an electrical signal when it reaches the next neuron. Electrical signals are impossibly fast, but neurotransmitters cannot cross a synapse that fast. So, the impulse is at its slowest point when it crosses the synapse.
The electrical impulse travels into the dendrites, the "input" of the neuron, and into the soma or "body" where the signal gets processed. From there, the processed signal travels down the axon or "output" and into the dendrites of another neuron.
When a stimulus causes positively charged ions to diffuse into the neuron.
A chemical signal.
it is impracticable because the time period of sampled impulse is 0 i.e t=0 and in real life it is impossible to produce a signal of 0sec.
