Figure D 7: Linear Frequency Sweep Formula and Waveform
Constants k0 is the sweep period and k1 and k2 are the starting and ending
frequencies.
Description This waveform can be expressed generally by the following formula.
V(t) + sin 2pf
Here f is the starting frequency, f
1
phase, and T is the sweep period.
To assure that the phases match when this waveform is iterated, the sweep
period is set to be close to an integer multiple of the reciprocal of the
average frequency
