WebSep 25, 2006 · The dither loop is superior to other OPLL designs, because it does not need the transmission of a residual carrier, it employs a 180deg/3-dB hybrid, an ac-coupled … Webalso can add a triangular dither signal to the current to reduce the mechanical hysteresis of the solenoid valve. This triangular waveform is filtered somewhat by the control loop, resulting in a quasi-sinusoidal waveform as shown in Figure 1. The frequency and amplitude of the dither waveform as well as the mean current value are programmed ...

WebNov 1, 2024 · The simulated and analytical results of acquisition time T f against frequency offset value Ω 0 are plotted in Fig. 8 (a)–(c) for several fixed values of the dither phase amplitude. Three different loop natural frequencies, i.e., f n = 100, 1000 and 10 000 kHz, are assumed in Fig. 8 (a)–(c), respectively. It is obvious that the analytical value of … WebAlso can have ‘dither jitter’ : phase wander when locked dither lock 20 CDR Dither Jitter Caused by need to track plesiochronous differences Dither jitter set by Latency of the loop usually 10-20 cycles Step size usually 10m-UI # of averages usually 16+ The last two along with transition density set the pusheen kitty
