Chirp frequency
WebFeb 19, 2024 · When mixing two chirps as you're doing, you will get a doubling of the frequency. Consider two chirps with a bandwidth B and pulse length τ. We'll use the complex form to simplify the math x 1 ( t) = e j π β τ t 2 x 2 ( t) = e j ( π β τ + ϕ) We introduced the arbitrary phase difference to be more general. Mixing this signals we get Web- Frequency Chirp generator: It is short-time sweep signal with linear or exponential frequency change, and adjusts start and stop frequencies by 3 presets and keyboard input. Chirp signal generation time and start delay time can be adjusted. Features: - Sine wave generator (Sine): Sine wave signal (Preset frequencies: 200Hz, 1kHz, 2kHz, 8kHz)
