In order for digital signals to be transmitted in a channel, pulse shaping must be performed in the baseband section of the transmitter to…

With the development of chip technology, the sampling rate of ADCs is becoming increasingly high, leading to digitalization getting closer…

Digital Video Broadcasting (DVB) is a complete digital television solution, which includes DVB-C (Digital Video Broadcasting - Cable), DVB…

Interpolation means increasing the sampling rate, hence it is called upsampling. Let the original sequence be x(n), the sampling rate be f_x…

The structure of a typical interpolator, with the filter located after the interpolation operation, means that the filter operates at a…

级联积分梳状滤波器（Cascade Intergrator Comb）是多速率信号处理中一种十分高效的数字滤波器。CIC 滤波器具有低通滤波器的特性，同时具有以下优势： 滤波器系数全为 1，设计时不需要存储滤波器系数，节省存储单元，同时使得滤波时只需要加法器和累加器…

💡 My graduation project topic is a multi-frequency digital upconverter, so I first simulated the DUC, aiming to upsample the audio signal…

The half-band filter is essentially an FIR filter, but nearly half of the coefficients are zero, thus reducing the computational load to…
