The Fourier transform of a function of time, s(t), is a complex-valued function of frequency, S(f), often referred to as a frequency spectrum. Any linear time-invariant operation on s(t) produces a new spectrum of the form H(f)•S(f), which changes the relative magnitudes and/or angles (phase) of the non-zero values of S(f). Any other type of operation creates new frequency components that may be referred to as spectral leakage in the broadest sense. Sampling, for instance, produc… WebApr 13, 2024 · Phase monitors.

WebFeb 14, 2024 · However, they can sum up together to reach the threshold and cause an action potential of the postsynaptic neuron. If an inhibitory signal (IPSP) also enters through another dendrite, this can counteract the two EPSPs and could prevent the neuron from firing action potential. This is an instance of spatial summation. WebThese transient membrane potential changes are called graded potentials, and they tend to occur in the dendrites of the neuron and in the soma of the neuron. And the size and the duration of the graded potentials is determined by the size and the duration of inputs-- both excitatory inputs and inhibitory inputs.
