The TMCS1100-Q1 signal chain has a spectral response atypical of a linear analog system due to its discrete time sampling. The 250-kHz sampling interval implies an effective Nyquist frequency of 125 kHz, which limits spectral response to below this frequency. Higher frequency content than this frequency will be aliased down to lower spectrums.

The TMCS1100-Q1 bandwidth is defined by the –3-dB spectral response of the entire signal chain which is constrained by the sampling frequency. Normalized gain and phase plots across frequency are shown below in Figure 9-7 and Figure 9-8, all variants have the same bandwidth and phase response. Signal content beyond the 3-dB bandwidth level will still have significant fundamental frequency transmission through the signal chain, but at increasing distortion levels
