Distortion Parameters - Part II— Lesson 2

This lesson covers distortion parameters of ADC. It discusses the effect of phase jitter at the output and provides an example of calculating the jitter in seconds for a dynamic range equivalent to the quantization noise from a 12-bit system. The lesson also explains the Signal-to-Noise Ratio (SNR) due to jitter and quantization noise, and how to calculate it. It further delves into the impact of different types of noise on the Analog-to-Digital Converter (ADC), including phase noise, jitter, and spurs. The lesson concludes with a discussion on how to calculate the noise level for any signal level and the overall system level noise.
