Digital electronic frequency division usually uses digital equipment such as digital signal processor or computer to calculate and process the input signal, and decomposes the input signal into several digital signals with different frequencies for output, so as to achieve the purpose of frequency division. This method can process signals with very high precision and achieve extremely high resolution and accuracy.

Analog electronic frequency division is to use analog circuits to process signals, decompose input signals into analog signals with different frequencies through oscillators, filters and other components, and then amplify and shape them to achieve the purpose of frequency division. Compared with digital electronic frequency division, analog electronic frequency division has some errors and drift, so it is difficult to achieve very high accuracy requirements. However, the analog circuit is simple in structure, suitable for processing low-frequency signals and can realize high-speed processing.
