Lesson plan
Multiburst
screen A multiburst waveform is a useful test pattern used to quickly ascertain the frequency response of a video system. The name derives from the multiple bursts of sine wave in the active video section of the waveform which are generated with (usually) increasing frequency, but identical in amplitude. The test pattern is usually input at the start of the signal chain and analysed at the end. By measuring the amplitude of each of the 'bursts' of waveform at the end of the video chain, spot measurements of the frequency response of the system can be obtained and errors in the response quickly identified.
