1, Principle of nixie tube dynamic display In fact, the dynamic display of nixie tube is an upgraded version of the static display of nixie tube. The segment selection signal given is the same, that is, which word is displayed, but the difference depends on which bit selection signal is given, that is, which nixie tube is displayed. Give ...

Written by @hzj //JinXing Project #2021.11.21 V1.0 1. Fixed point positioning of filter and use of Beyond compare (1) Why fixed-point positioning? 1. Fixed point: the existence of fixed point is due to the binary operation inside FPGA. The decimal point (floating-point data) in the actual operation cannot be accurately represented by bi ...

1 DDS principle 1.1 interpretation in the book DDS (Direct Digital Synthesizer) technology is a new frequency synthesis method. It is a frequency synthesis technology that directly synthesizes the required waveform from the phase concept. It directly generates various signals of different frequencies and different waveforms by controlling ...

1. What is FIFO          FIFO is a first in first out data buffer, which is widely used in logic design. FIFO design can be said to be a common sense design that logic designers must master. FIFO is generally used to isolate places where the read-write bandwidth on both sides is inconsistent or the bit w ...

1. What is SPI protocol          SPI (Serial Peripheral Interface) communication protocol is a synchronous serial interface technology proposed by Motorola Company. It is a high-speed, full-duplex, synchronous communication bus. Only four pins are used to control and transmit data in the chip. It is wide ...
