Making a Guitar Automatic Tuner Based on Arduino

One of the most important things when playing guitar is making sure the instrument is in tune. Even the best guitarists won’t sound any good with an out-of-tune guitar. Manual tuning with a standard tuner has always been common, but the automatic tuner makes things easier and more fun! This Arduino based project will tune […]

Analysis of discrete-time signals and systems

Theory must be combined with practice! Therefore, in 2018, there will be the sixth part of the explanation, the purpose of which is to let students see how the theoretical knowledge learned can be realized by programming in the computer. Since it can be realized by programming, it can certainly be completed by programmable devices, […]

Implementation of Gaussian filtering algorithm in FPGA

1. Realization of Gaussian filtering algorithm The mean / median filter mentioned above has the same weight for each pixel in the filter window. However, the noise often appears as isolated pixels or blocks of pixels with abnormal visual effects in the image, so it must not be evenly distributed. Here we first introduce a […]

MATLAB and FPGA design of FSK modulation technology

FSK modulation FSK uses the frequency of the carrier to represent baseband information. For example, in the 2FSK system, the single frequency signal F1 represents information 0 and the single frequency signal F2 represents information 1. According to whether the carrier phase is continuous during symbol conversion, it is divided into discontinuous phase FSK and […]
