Chirp method
WebIt is easier to provide sine-sweep (or CHIRP). Unfortunately I think this input signal is not compatible with direct frequency domain analysis, because each frequency is only excited during a specific timeframe and the Foerier transform assumes a harmonic oscilation during the entire sample-time. 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 more The basic definitions here translate as the common physics quantities location (phase), speed (angular velocity), acceleration (chirpyness). If a waveform is defined as: See more A chirp signal can be generated with analog circuitry via a voltage-controlled oscillator (VCO), and a linearly or exponentially ramping control voltage.
