What else can I help you with?
What is bandwidth of a impulse signal?
The bandwidth of impulse signal is infinity.because upper frequency is infinity.
Is impulse function is an energy signal or a power signal or both Explain?
it can not be both!
What is the instantaneous sampling?
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.
Why would a neuron not send an impulse?
If a neuron is not sending out an impulse or signal, this means the neuron is at rest. Neurons send signals electrochemically.
How does a nervous impulse vary from a hormone signal?
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)
What is the impulse response of R-L circuit?
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.
State why there is a brief delay in the transmission of an impulse across the synapse?
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.
What is the path of an electrical impulse as it moves through a neuron?
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.
The nerve impulse travels as an electric charge and as it nears the synapse it becomes?
A chemical signal.
When is an impulse an electrical signal?
When a stimulus causes positively charged ions to diffuse into the neuron.
Why impulse sampling is impracticable?
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.
How are hormones similar to neurotransmitters?
A neural impulse is similar to an electrical signal in three ways: 1. there are electrical voltages involved in the movement of the neural impulse; 2. an electrical signal can convey information, as can a neural impulse; 3. an electrical signal can cause an action, like a car starter switch starting the engine, and a neural impulse can cause a muscle to contract to move a limb. (note that with respect to the voltages involved in the neural impulse, the voltages are created by the movement of chemicals, charged particles called ions, somewhat similar to how batteries produce voltages.) (also note that the neural impulse is the signal which moves along the axon, as an action potential.)
