Simplified schematic of the time-locked subsampling (TLSS) algorithm.
Frequency domain plot showing (a) the original band-limited signal and subsampling signal and (b) convolution of the band-limited signal and the subsampling function , resulting in a repeating pattern of the original signal with reflection symmetry around zero Hertz.
Block diagram of the 300 MHz FT-EPR system. The spectrometer can be configured for both coherent pulsed excitation and stochastic excitation.
Block diagram of the firmware programmed into the Altera CPLD to transfer four data bytes from the A/D converter as one 32-bit word into the data acquisition card.
Received FID signals with zero gradient fields for (a) coherent averaging and (b) stochastic excitation for NMP-TCNQ. field was offset by 0.524 mT and the field is 1.0 G. Solid line is the term and dashed line is the term.
2D image of two samples of NMP-TCNQ using the coherent averaging configuration. 37 projections were acquired for the back projection reconstruction, with the gradient fields set to .
