LFER4 model[edit]
Here we describe the "Low frequency excess response" 4 model. If we write the input signal (power) on a bolometer as , the bolometer physical impedance can be written as , where is the angular frequency of the signal and is the complex intrinsic bolometer transfer function. For HFI the bolometer transfer function is modelled as the sum of four single pole low-pass filters: . The modulation of the signal is performed with a square wave, written here as a composition of sine waves of decreasing amplitude: , where we have used the Euler relation and is the angular frequency of the square wave. The modulation frequency is and was set to Hz in flight. This signal is then filtered by the complex electronic transfer function . Setting we have . This signal is then sampled at high frequency, (). Here is one of the parameters of the HFI electronics and corresponds to the number of high frequency samples in each modulation semi-period. In order to obtain an output signal sampled every seconds, we must integrate on a semiperiod, as done in the HFI readout. To also include a time shift , the integral is calculated between and (with period of the modulation). The time shift is encoded in the HFI electronics by the parameter , with the relation .
After integration, the n-sample of a bolometer can be written as , where
The output signal in equation eqn:output can be demodulated (thus removing the (-1)n) and compared to the input signal in equation bol_in. The overall transfer function is composed of the bolometer transfer function and the effective electronics transfer function, : .
