Though it can be considered as an extension of the IBM patchwork technique, it has a great advantage over the latter in that the watermark modulation depth
can be selected to be less under the same imperceptibility requirement.
As the modulation frequency increases, the switching response becomes quicker, but the modulation depth
Due to its long read-range and its high modulation depth
, the HITAG S IC developed by Philips Semiconductors is well suited for use in animal identification because it overcomes the large amounts of electronic noise and interference typically found in animal processing plants.
transmitter power and modulation depth
over the range of
It is ideal for use with the resonant phase and amplitude modulators, providing up to 30 dBm of output power for high modulation depths
(up to three radians) up to a frequency of 2.
