Abstract
The data signal modulates the period of a carrier in a linear fashion to obtain the same benefits offered by FM tape recording. A discriminator for this type of modulation can have significantly less spurious output at the carrier and its second harmonic than pulse-counting FM discriminators. This may allow wider modulation bandwidth or simplify post-detection filtering. Digital techniques can be employed to yield a system with a very stable overall transfer function.
