Systems and methods for delaying an input signal are described. A device can receive an input signal. The device can activate a state of at least one circuit element among a plurality of circuit elements. The plurality of circuit elements can be connected to a plurality of segments of a transmission line. The device can output the input signal to the transmission line. The device can receive a reflection of the input signal. A delay between the reflection and input signal can be based on the activated state of the at least one circuit element among the plurality of circuit elements. The device can output the reflection of the input signal as an output signal.
