A simple and straightforward application of the formalism of electronic holography to various classes of coherent optical effects is shown to confirm recently observed phenomena. Specifically, the formalism in the time domain is applied to illustrate dynamic and static pulse echoes as well as time-inverted and nontime-inverted recall of general signals, including a sawtooth and Gaussian pulse. The case of multipulse echoes, in which the echoes appear in odd order, is also explored.
