These systems operate on a wide variety of continuous time signals , which include speech , medical imaging , sonar , radar , electronic warfare , instrumentation , consumer electronics and telecommunications systems ( terrestrial and satellite ) . one of the key to the success of these systems has been advances in the development of the font end of the electronic systems - analog - to - digital converters ( a / d ) which converter the continuous - time stimuli signals to discrete - time binary - coded form 这些系统可广泛地应用于处理连续时间信号,包括语音、医学成像、声、雷达、电子对战、仪器、消费电器、远程通讯(地面和卫星)等,而这些系统成功的关键因素之一就是电子系统的前端部件? ? a d取得了长足的进步( a d把连续时间信号转换成离散时间、二进制编码的数字信号,便于后级精确的数字信号处理) 。
