And now suppose my resolution actually varys over x: at x=0.5, the smearing function is a Gaussian with sigma_conv=0.5, but at x=1.5, … 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.

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… WebA transform approach based on a variable initial time (VIT) formulation is developed for discrete-time signals and linear time-varying discrete-time systems or digital filters.
