A method comprising: partitioning an input stream of digital samples {D 0, D 1, D 2, D 3,...} into N sub-streams (114,116,214,216,218), wherein N is three, such that the first sub-stream includes a first pair of adjacent digital samples {D 0, D 1} from the input stream and each subsequent Nth pair of adjacent digital samples {D 2N, D 2N+1} from the input stream, and the second sub-stream includes a second pair of adjacent digital samples {D 2, D 3} from the input stream and each subsequent Nth pair of adjacent digital samples {D 2N+2, D 2N+3} from the input stream; for each of the N sub-streams converting the sub-stream of digital samples into a respective sub-stream (124,126,224,226,228) of analog samples such that each analog sample in the sub-stream of analog samples is captured from a stable portion of a corresponding digital sample in the sub-stream of digital samples, and where the sub-stream of analog samples contains one analog sample in each time period of duration ~2T s; and providing the sub-stream of analog samples to a respective one of N inputs of a controlled switch (110,210), the controlled switch having a single output; and controlling with a control signal the controlled switch to switch between N different states, the control signal having a period of ~2 N T s, where in each state a respective one of the N inputs is connected to the single output, wherein while the controlled switch is in any one of the N different states, a data transition occurs between two adjacent analog samples in the sub-stream that is provided to the one of the N inputs that is connected to the single output, wherein the single output yields a high-bandwidth analog signal that contains one analog sample {A 0, A 1, A 2, A 3,...} in each time period of duration approximately T s, and any pair of adjacent analog samples in any one of the N sub-streams substantially determines a corresponding pair of adjacent analog samples in the high-bandwidth signal; wherein converting each sub-stream of digital samples into its respective sub-stream of analog samples is performed in a respective sub-DAC driven by a clock (120,220) at a rate identical to a rate of the control signal; and wherein an order of the digital samples in the input stream is identical to an order of the analog samples in the high-bandwidth analog signal. partitioning an input stream of digital samples {D 0, D 1, D 2, D 3,...} into N sub-streams (114,116,214,216,218), wherein N is three, such that the first sub-stream includes a first pair of adjacent digital samples {D 0, D 1} from the input stream and each subsequent Nth pair of adjacent digital samples {D 2N, D 2N+1} from the input stream, and the second sub-stream includes a second pair of adjacent digital samples {D 2, D 3} from the input stream and each subsequent Nth pair of adjacent digital samples {D 2N+2, D 2N+3} from the input stream;
