摘要： A system and method for processing signals determines rise and fall times of a driving signal, compares the rise and fall times to desired values, and independently controls the rise and fall times to equal the desired values. The rise and fall times may be controlled by generating one or more first correction bits based on a difference between the rise time and a corresponding one of the desired values, generating one or more second correction bits based on a difference between the fall time and a corresponding one of the desired values, and then separately applying the bits to independently control the rise and fall times of the driving signal. The driving signal may be an I/O signal or another type of signal.

摘要： A CMOS amplifier for optoelectronic receivers, the amplifier comprises two transimpedance amplifiers and two differential amplifier latches. One of the two transimpedance amplifiers has an input port to receive a current signal, such as, for example, a current signal from a photodetector, and provides a output voltage indicative of the received current signal. The other of the two transimpedance amplifiers may be viewed as having no input signal, so that it provides a reference voltage. The two transimpedance amplifiers are in close proximity to each other, so that power supply noise is a common mode signal in the output voltages of the two transimpedance amplifiers. The differential amplifier latches reject the common mode signal by comparing the reference voltage to the output voltage, and provide output logic voltages indicative of binary hard decisions. Two differential amplifier latches are employed, each with an evaluation phase on alternate transitions of a clock signal, so as to provide a higher throughput than if only one differential amplifier latch was employed.

摘要： The call reestablishment system functions to provide the user with the ability to replace an existing communication connection with another equivalent communication connection in an automated manner that does not disrupt the existing call and to also provide the user with the ability to create a replacement communication connection using a different common carrier as the billing source. The call reestablishment system is activated when a party on an existing communication connection generates feature activation control signals indicative of the desire to access the call reestablishment system. The serving communication system, in response to receipt of the feature activation control signals, enables the requesting party to input data indicative of the nature of the call reestablishment that is required. The call reestablishment system is responsive to this data for creating a replacement communication connection for the existing communication connection and, once the facilities are in place to enable the calling and called parties to communicate, the call reestablishment system automatically transfers the calling and called parties from the original communication connection to this newly established communication connection in a manner that is transparent to the parties and without loss of any communications.
