I like that definition. By the way, according to Don White Consultants Inc., in their 1976 book on EMI, "The quasi-peak detector is a carryover of the EMC instrumentation in use many years ago. At that time, most of the potential EMC victims were AM broadcast receivers and potential EMI sources were both manmade impulsive and stead-state in nature. It was observed that by weighting the detector rise and fall time, the impact of electrical noise to the broadcast receiver-human ear combination could be more directly interpreted with EMI receiver readings."
Analogue type television receivers suffered similar susceptibility to impulsive noise because the video carrier was amplitude-modulated and had a much wider bandwidth compared to an AM receiver.
