    摘要： A pulse width modulation (PWM) signal generator generates a PWM signal having a specified effective PWM duty resolution for a corresponding cycle window. The PWM signal generator receives an N-bit value representing a duty to be implemented and sets values X and Y to the M least significant bits and the N-M most significant bits, respectively, of the N-bit value. The value M can be determined based on the value N and a maximum implementable frequency of a clock signal used to time the generation of each PWM cycle. The PWM signal generator generates a cycle window of 2M PWM cycles, each PWM cycle of the cycle window having a duty of either Y or Y+1. The number of PWM cycles in the cycle window having the duty Y+1 is based on the value X and the PWM cycles having a particular duty are contiguous within the cycle window.

    摘要： Systems and methods for a readiness dialog box for a call over network (CON) are provided. In some embodiments, the readiness dialog box is presented to the callers prior to the onset of the call. It presents the other participant's and their status. For example, it may indicate which participants are online, but not yet ready, those who are ready, and those not available. It also enables the caller to send messages (both preconfigured and customized) to the other participants. Once sufficient participants have joined, the call may start. Sufficiency of participants could include a quorum of individuals, may require that specific participants are ready, everyone is ready, or may be time dependent. The participant requirements may be configured by the individual setting up the call based upon call type.
