Sammanfattning
New spectroscopic techniques, such as photocurrent detected two-dimensional spectroscopy, require analog to digital converters with very high dynamic range. In such techniques, one measures the linear as well as the nonlinear response from the sample that are excited by modulated light. The linear and nonlinear signals are detected at different modulation frequencies. Typically, the linear signal is 100 to 1000 times larger than the nonlinear signal. Thus, ADCs with very high dynamic range are necessary to measure both the signals simultaneously. It is required to digitize and store the measured signals to be able to transfer the data to a computer in order to process the information.
