Abstract

The invention relates to a Fourier transform system. The system comprises a first signal processor and an analog signal processing unit; the first signal processor receives an input signal, expands frequency components of the input signal in the time domain according to the frequency relation, and then outputs the expanded signal; and the analog signal processing unit is connected with the output end of the first signal processor, receives the expanded signal output by the first signal processor, and demodulates and filters the expanded signal to obtain a first Fourier transform result. According to the Fourier transform system, the first signal processor expands the frequency components of the input signal in the time domain, the input signal is converted to a narrowband signal, and the analog signal processing unit can process the narrowband signal to complete Fourier transform. The Fourier transform system overcomes the disadvantage that the working bandwidth of traditional digital signal processing is narrow.

Description

technical field [0001] The invention relates to the technical field of signal processing, in particular to a Fourier transform system. Background technique [0002] With the rapid development of computer and information science, digital signal processing (Digital Signal Processing, DSP) technology came into being, forming an independent subject department. Simply put, digital signal processing is the use of computers or special processing equipment to process signals by numerical calculation methods such as acquisition, transformation, synthesis, evaluation and identification, so as to achieve the purpose of extracting information and facilitating applications. [0003] In the field of engineering, engineering signals are complex components composed of multiple frequency signals. The analysis of time-domain signals contains the same amount of information, while the frequency-domain analysis of some concerned quantities will be more intuitive and easy to operate and process....
