Understanding Auditory Spectro-Temporal Receptive Fields and Their Changes with Input Statistics by Efficient Coding Principles

Figure 6

Simulation of temporal receptive field TRF, when the spectral dimension is omitted.

The same stimulus ensemble is used as in Figure 3A, except the factor in equation (12) to ensure translation invariance of correlation. (A;B) Demonstration of transforming an acausal temporal filter (A) to its causal minimum-phase counterpart (B) at a relatively high input SNR. (C) TRF for a relatively low input SNR.
