21. The clock frequency is then adjusted to reduce the offset gradually, creating a feedback loop. 22. Clock frequency was not increased at launch and remained between at 1.5 to 1.9 GHz.23. High-performance integrated circuits have traditionally been characterized by the clock frequency at which they operate. 24. Since frequency is inversely proportional to clock period, the clock frequency increases as a result. 25. Firstly, the higher clock frequency achievable offset the loss. 26. The system CPU clock and video hardware are synchronized to one-half the NTSC clock frequency . 27. Additionally, some computers did not derive their TOD clock frequency from the mains power source. 28. These properties enable a better balancing of clock frequencies . 29. Typical clock frequencies are 100 and 133 MHz. 30. All flip-flops operate at the given clock frequency .
