摘要： A noise reduction system is used in a BTSC system to reduce noise of an audio signal. The noise reduction system has an audio spectral compressing unit that has a filter and a memory in the approach of the digital processing. The filter is arranged to filter an input signal according to a transfer function, a variable d, and several parameters b0/a0, a0/b0, b1/b0 and a1/a0. The memory is arranged to store the parameters.

摘要： An image compression and decompression method encodes and decodes pixel data based on a color conversion method. Based on the relationships of corresponding color components of two adjacent pixels, the corresponding color components are encoded either by a white and black modification, a down-sampling or an edge modification. Based on the relationships of encoded color components of the two adjacent pixels, the corresponding encoded color components are decoded either by an inverse white and black modification, an up-sampling or an inverse edge modification.

摘要： A NICAM system includes a NICAM deframer, a FIFO buffer and a symbol rate conversion (SRC) unit. The NICAM deframer obtains multiple deinterleaved symbols according to a strobe signal and a data signal in each timing and expands the deinterleaved symbols to corresponding multiple pulse code modulation (PCM) symbols. The FIFO buffer temporarily stores the symbols and outputs the PCM symbols at a local timing, rate. The SRC unit determines whether a SRC function is enabled according to the statuses of the symbols in the FIFO buffer every a constant time interval. When the SRC function is enabled, the SRC unit interpolates the PCM symbols to obtain multiple new PCM symbols and outputs the new PCM symbols at the local timing rate.
摘要翻译： NICAM系统包括NICAM解帧器，FIFO缓冲器和符号速率转换（SRC）单元。 NICAM解帧器根据每个定时中的选通信号和数据信号获得多个解交织的符号，并将解交织的符号扩展到相应的多个脉码调制（PCM）符号。 FIFO缓冲器临时存储符号并以本地定时速率输出PCM符号。 SRC单元每隔一定时间间隔确定是否根据FIFO缓冲区中的符号的状态启用SRC功能。当启用SRC功能时，SRC单元内插PCM符号以获得多个新的PCM符号，并以本地定时速率输出新的PCM符号。
