1, complete solution and full response are commonly used concepts in signal processing and system analysis. The complete solution means that the output response of the system is obtained by some mathematical operation on the input signal of the system. Full response means that the system comprehensively considers the responses of all possible input signals and obtains the overall response of the system.

2. In the calculation method, the complete solution is usually obtained by solving the difference equation or differential equation of the system, so as to obtain the output expression of the system. Total response is to get the output signal of the system through the convolution operation of the impulse response of the system and the input signal.

3. In a sense, the complete solution pays more attention to the specific output of the system, and obtains accurate output results through analytical or numerical methods. Full response pays more attention to the overall performance of the system and considers the response of the system to all input signals.
