Question:

In section 11.5.1 on page 396 it was shown that a pathway with Δp = -3 could be selected with the following four-step cycle.
pulse phase: [0°, 90°, 180°, 270°] rx phase: [0°, 270°, 180°, 90°].
Show that this cycle rejects pathways with Δp = -1 and Δp - 0, but selects a pathway with Δp = +5.
