ABSTRACT:
For determining a signal response characteristic of a device, a first signal is varied with a first function of time and simultaneously a second signal is varied with a second function of time, wherein the first function is different from the second function. The first and second signals are coupled to the device, wherein the device is exposed to a time-dependent disturbance signal. A signal response is received from the device in response to the first and second signals and the time-dependent disturbance signal. The signal response characteristic is derived by analyzing the received signal response in conjunction with the first and second signals, or a signal derived therefrom, and at least partially removing the time-dependent disturbance signal using the received signal response and the first and second signals, or a signal derived therefrom.
