[The discrimination of frequency-modulated signals under free behavior conditions in cats]
Abstract:
Cats were trained to discriminate stimuli linearly modulated in frequency. Discrimination threshold were measured with limit method. The differential threshold, delta F/F0.100%, turned out to be constant and equal to be about 3% in the range of 1.5-6.5 kHz with no dependence on both temporal structure and frequency variation rate.

01:21Frequency-dependent Selection
When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.Positive Frequency-Dependent SelectionIn positive...

Accurate signal sampling and reconstruction are crucial in various signal-processing applications. A time-domain signal's spectrum can be revealed using its Fourier transform. When this signal is sampled at a specific frequency, it results in multiple scaled replicas of the original spectrum in the frequency domain. The spacing of these replicas is determined by the sampling frequency.
If the sampling frequency is below the Nyquist rate, these replicas overlap, preventing the original signal...
