PAM-2 has been widely used in various serial communication interfaces over the years due to its simplicity, robustness and lower cost to implement. The signal level remains constant during the bit interval, which helps in maintaining signal integrity with good margin. For decades it has been the...
Analog Applications Journal Communications The intricacies of signal integrity in high-speed communications By Rick Zarr Member Group Technical Staff, Signal Chain Applications Introduction As communication rates continue to increase, Figure 1. Example signals showing various transmission-line effects data is...
Signal Integrity simulations, e.g., with IBIS models, are useful to optimize the value of the series resistor by including the receiver and board parasitics. Further, with simulations, the series termination can be proved under corner conditions like the weak and strong process corners of the ...
Another point to note is the value of the pull-up/pull-down resistors used in the digital communication lines. These resistors are used to ensure a proper logical level at the digital input/output, and their value may have an impact on the overall system power consumption. Usin...
Thus, a compromise must be made between signal integrity and system cost. SENSOR LINEARIZATION Many sensors exhibit a deviation from an ideal (linear) relationship between input and output. For example, a given change in temperature does not give rise to the same change in EMF for most ...

In the case of high pass filters at 0.5 Hz, the signals will be affected by a not negligible phase shift up to 5Hz (one decade above). Even if the filters used have a very steep Roll-Off, a cut-off frequency of 0.5Hz compromises the integrity of the signals acquired in the band ...
HARQ is a technique well-known to those of ordinary skill in the art, wherein the integrity of packet transmissions may be checked at the receiving side for accuracy, e.g., utilizing any suitable integrity checking mechanism, such as a checksum or a cyclic redundancy check (CRC). If the ...
However, from a signal integrity standpoint, unconnected via stubs have a far larger effect on the signal than the geometry of the via itself. This note explains how the Polar Si9000 can help you check if, at your desired bit rate or operating frequency, you need to take steps to reduce...
Until recently the PDA gave estimated results during testing only according to the Case Method which are a series of closed form solutions for capacity, installation stresses, energy transfer, and pile integrity. In recent years as computational computing power has increased, faster reporting of ...
