%X The instantaneous frequency can be used to provide information about how the
frequency content of the phonocardiogram signal varies in time, in order to characterize
the heart sounds and murmurs. The instantaneous frequency of a signal can be calculated
from the discrete Hilbert transform, computed through the moving discrete Hartley
transform, which reduces the computation time. To compute in real time the instantaneous
frequency, the algorithms have been implemented in a FPGA device, exploiting the high
performance and flexibility of reconfigurable hardware. The results obtained from the
FPGA show high accuracy in comparison to those computed with Matlab
