You can think of blip as one tiny pulse from a machine: a dot that flashes once on a screen, with a short high beep at the same moment, and then nothing. It is small, it is quick, and it is finished before you can look twice. Everything else the word does grows out of that one flash — the machine that makes the sound, the light that switches on and off, and a short dip in life that is over as fast as the dot.
From the word’s history
Wiktionary records blip as onomatopoeic: the word was made to imitate the noise itself. That is why the machine's short note sits at the centre of the word.
Wiktionary 標示 blip 是狀聲字，也就是照著聲音造出來的。唸 blip 的時候，嘴巴幾乎就在模仿機器的那一聲。所以這個字的中心一直是那一聲，其他用法都從那一聲延伸出去。
