设计了一基于现场可编程门阵列（FPGA）的低频数字式相位测量仪。该测量仪包括数字式移相信号发生器和相位测量仪两部分，分别完成移相信号的发生及其频率、相位差的预置及数字显示、发生信号的移相以及移相后信号相位差和频率的测量与显示几个功能。其中数字式移相信号发生器可以产生预置频率的正弦信号，也可产生预置相位差的两路同频正弦信号，并能显示预置频率或相位差值；相位测量仪能测量移相信号的频率、相位差的测量和显示。两个部分均采用基于FPGA的数字技术实现，使得该系统具有抗干扰能力强,
可靠性好等优点。()

说明： Owing to the broad application value of audio
watermarking in remote transmission and mobile
extraction, it is very important to study watermarking
approaches against A/D and D/A conversion. Based
on wavelet decomposition and cepstrum technology,
an audio watermarking algorithm is proposed where
the low-frequency wavelet coefficients are chosen for
cepstrum transforming. Then, the obtained cepstrum
data shows stable for watermark hiding by the
methods of edging data cutting and statistical mean
modification. The synchronization is not required in
the algorithm. Experimental results show that the
proposed algorithm can resist on the attack of A/D
and D/A successfully with features of large capacity
and zero bit error. It will be helpful for the mobile
audio in secure broadcast and management in the
