Chirp sine wave
WebThe spectrum of a chirp pulse describes its characteristics in terms of its frequency components. This frequency-domain representation is an alternative to the more familiar … WebOct 1, 2000 · To obtain the value of f1 , divide the sine wave’s start (lowest) frequency in hertz by the sample rate. To obtain f2 , divide the sine wave’s stop (highest) frequency by the sample rate. You need a sample rate that will produce a reasonable representation of a sine wave at the stop frequency.
