One of the key attributes of transfer function analysis is that it provides a means of measuring the frequency response of a device using any broadband signal. Making it the ideal choice for analyzing devices like smart speakers, smartphones, etc.
In this technote we discuss the Transfer Function measurement in general, followed by some practical examples of applying this measurement technique to some difficult audio test problems – testing smart speakers and microphones with digital output (PDM and Bluetooth®). Many smart devices incorporate DSP algorithms that require the use of speech signals, and some are designed to block sinusoidal signals altogether. Transfer function analysis greatly simplifies measuring the frequency response of such devices.
