基于码本映射的语音带宽扩展算法研究

在现代通信系统中,电话语音的频带被限制在300 Hz~4 kHz的范围内,带来了语音可懂度和自然度的降低。为了在不增加额外成本的前提下提高语音的可懂度和自然度,进行了电话语音频带扩展的研究。提出了一种改进的基于码本映射的语音带宽扩展算法:在码本映射的过程中,使用加权系数来得到映射码本。客观测试结果表明,用此算法得到的宽带语音的谱失真度比用一般的码本映射降低至少2%。主观测试结果表明,用此算法得到的

基于开关电容技术的锁定放大器设计

锁定放大是微弱信号检测的重要手段。基于相关检测理论,利用开关电容的开关实现锁定放大器中乘法器的功能,提出开关电容和积分器相结合以实现相关检测的方法,并设计出一种锁定放大器。该锁定放大器将微弱信号转化为与之相关的方波,通过后续电路得到正比于被测信号的直流电平,为后续采集处理提供方便。测量数据表明锁定放大器前级可将10-6 A的电流转换为10-1 V的电压,后级通过带通滤波器级联可将信号放大1×105
