51单片机的实用子程序，包括片内及片外ram初始化，滤波程序，多字节算术运算程序，排序程序，以及51定点运算子程序库，浮点运算子程序库等等。-51 SCM utility subroutine, including the chip and chip ram initialization, filtering procedures, procedures for multi-byte arithmetic operations, sorting procedures, and 51 fixed-point computation subroutine library, subroutine library floating-point operations and so on.

With the program AD9854C.exe one can set and tune the frequency in CW-mode. For use as a receiver LO also IF can be given and the both possible receiving frequencies are printed on the screen. The level in Q-outputs can be varied by giving the wanted attenuation in dB. This function is done by controlling a 12b digital multiplier in the device. In this case the level decreases somewhat with increasing frequency as it does in DDS devices. Alternatively the inverse sinc correction can be chosen, in which case the output is flat and high. -With the program AD9854C.exe one can set and tune the frequency in CW-mode.
