In addition to the conversion between digital and analog signals, the conversion of voltage or current, the conversion of switching quantities, and the conversion of frequency or pulse width, there are some other common signal conversion methods, FBM09 include:

Pulse code modulation (PCM) : discretizes the amplitude of an analog signal and converts it into a digital signal through sampling and quantization.

Bitstream coding (BSC) : Converts digital signals into binary bitstreams for digital signal transmission and processing.

Quadrature amplitude modulation (QAM) : Converts digital signals into analog signals by quadrature amplitude modulation, which is mainly used in wireless communication systems.

Modem: Converts the digital signal to analog signal by modulation, and then converts it to digital signal by demodulation.

Digital Signal Processor (DSP) : The use of digital signal processing algorithms to process digital signals, such as filtering, noise suppression, noise reduction, etc.

Fast Fourier transform (FFT) : Converts a digital signal in the time domain to a digital signal in the frequency domain, often used in signal analysis and processing.

These modes have their applicable scenarios and application ranges. According to the specific application requirements and system requirements, the FBM09 can choose a suitable signal conversion mode to improve the quality and efficiency of signal transmission.
