An ADC testbench in Simulink is a simulation environment that allows you to test and validate the performance of an Analog-to-Digital Converter (ADC) using simulated input signals. A typical ADC testbench in Simulink includes the following components:

The basic idea of the ADC testbench is to apply a known input signal to the ADC and compare the output signal with the expected output signal. The difference between the two signals is called the error signal. By analyzing the error signal, you can evaluate the performance of the ADC and identify any issues or deficiencies.

The testbench can be run in several ways, either by providing a continuous signal and measuring the output or by providing different test cases to the ADC and analyzing the output for each test case.

Remember that the Simulink version you are using might not have the ADC block pre-installed, so you might need to add it to the library or use a third-party library for the ADC block.
