延迟线 

An analog delay line is a network of electrical components connected in series, where each individual element creates a time difference or phase change between its input signal and its output signal. It operates on analog signals whose amplitude varies continuously. An example is a bucket-brigade device. Other types of delay line include acoustic (usually ultrasonic), magnetostrictive, and surface acoustic wave devices. A series of resistor-capacitor circuits (RC circuits) can be cascaded to form a delay. Delay Lines are in stock at Tenco Electronics. Tenco offers inventory, pricing, & datasheets for Delay Lines.
