Theta frequency - Study guides, Class notes & Summaries

Nyquist Theory - The specification of the minimum sampling rate used, in relation to the highest frequency signal recorded The sample rate must be twice that of the highest frequency to be recorded. For LFF, the corresponding time constants for LFF cutout freq. of 3 hz would be - .05 seconds The most prominent clinical feature of Dilantin toxicity - Ataxia Ataxia - lack of muscle coordination Agnosia - the inability to recognize familiar objects. Apraxia - inability to perform particular ...
