在无线通信中使用跳频技术是军事通信中最主要的抗干扰手段之一, 而如果系统中能使用合适的中心频率可以快速跟踪跳频变化的带通滤波器将可以明显改善系统的抗干扰性能。文中从实际应用出发, 比较了几种可用于实现带通滤波器快速变频的方案, 选择了简单、实用的开关电容阵改变带通滤波器中心频率的方案-The use of frequency hopping in wireless communication technology is the most important anti-jamming in military communications, one of the means, and if the system can use the appropriate center frequency can be fast-tracked changes in frequency-hopping band-pass filter will be able to significantly improve the system anti-jamming性能. This paper from the actual application, the comparison of several band-pass filter can be used to achieve the rapid conversion of the program, choose a simple, practical switched capacitor array to change the center frequency of band-pass filter program

ST7787 chip SPEC, BYD 2.4inchLCM the SPEC. The ST7787 is a single
ST7787 芯片的SPEC,比亚迪2.4inchLCM的SPEC。The ST7787 is a single-chip controller/driver for 262K-color, graphic type TFT-LCD. It consists of 720 source line and
320 gate line driving circuits. This chip is capable of connecting directly to an external microprocessor, and accepts Serial
Peripheral Interface (SPI), 8-bits/9-bits/16-bits/18-bits parallel interface. Display data can be stored in the on-chip display
data RAM of 240x320x18 bits. It can perform display data RAM read/write operation with no external operation clock to
minimize power consumption. In addition, because of the integrated power supply circuits necessary to drive liquid crystal,
it is possible to make a display system with the fewest components.-ST7787 chip SPEC, BYD 2.4inchLCM the SPEC. The ST7787 is a single-chip controller/driver for 262K-color, graphic type TFT-LCD.
