8.3.3.3 Frequency Response

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

The TMCS1100-Q1 bandwidth is defined by the –3dB 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 8-7 and Figure 8-8, all variants have the same bandwidth and phase response. Signal content beyond the 3dB bandwidth level still has significant fundamental frequency transmissions through the signal chain, but at increasing distortion levels
