Abstract:
1. A pulse generating circuit comprising: a tank circuit configured to resonate; and a control circuit coupled to the tank circuit and configured to cause the tank circuit to produce a stream of substantially sinusoidal shaped resonant periodic pulses that substantially conform to a graph comprising a unit circle and two tangents to the circle that intersect the circle at points A and B, respectively, and that intersect each other at a point C, wherein the longer arc on the circle between the point A and the point B represents the interval between the pulses, wherein the distance from the point A to the point C plus the distance from the point B to the point C represents the off interval between the pulses, wherein tan and wherein θ is one-half of the angle BCA and wherein r is the length of the longer arc and is not equal to unity.
