This type of circuit is usually used to obtain a low-cost non-isolated low-current power supply. Its output voltage can usually range from a few volts to more than 30 volts, depending on the Zener vol...
Advanced manufacturing techniques and smaller process geometries drive the core voltage to lower levels. This trend, combined with existing I/O standards, has led to the design of multiple voltage rai...
My tutor has a new theory that can improve the efficiency of convolution calculations, mainly in terms of speed and accuracy. It is better than the traditional convolution using FFT, but the applicabl...
When using fixed-point DSP for floating-point calculations, Q value calibration is used. How does DSP implement Q value? For example, in the following program,let x = 3.0, y = 3.1, then the floating-p...
