WebAug 21, 2015 · You can use a linear translation to get the sample in the range of values that you want: s = s_center + s_peak * sin (theta) / 2, but you will need to calculate your s_ave and s_peak from your center voltage, V_center, and your peak to peak voltage, V_peak. So there are two translations. A chirp is a signal in which the frequency increases (up-chirp) or decreases (down-chirp) with time. In some sources, the term chirp is used interchangeably with sweep signal. It is commonly applied to sonar, radar, and laser systems, and to other applications, such as in spread-spectrum communications (see … See more The basic definitions here translate as the common physics quantities location (phase), speed (angular velocity), acceleration (chirpyness).
