Audio Signal Conditioner Circuit

The circuit comprises of a phase detector, loop filter, Numerically Controlled Oscillator NCO , and two clock dividers. The circuit was stabilized to produce the frequency in the audio frequency range of 9. This agreed with the classical phase-locked loop model for the system. The stable long-term frequency clock was verified on the FPGA to generate the required locking frequency.

User Name Stay logged in? With a given loop filter and charge pump current, the loop bandwidth will depend on the phase comparison frequency WFQ, in your terms. The lower the WFQ, the higher the division ratio of the feedback divider, the more the whole loop gain curve shifts down and the slower the loop response. The damping of the loop response also depends on it. It seems like the loop couldn't keep up with the drift of the output sample rate of the CD player for too low values of WFQ. Since you apparently have a way to measure jitter, you could check what setting of the reset delay gives you least jitter. Or have you already done that? That wasn't clear to me.

Electrical Engineering Stack Exchange is a question and answer site for electronics and electrical engineering professionals, students, and enthusiasts. It only takes a minute to sign up. Connect and share knowledge within a single location that is structured and easy to search. These interfaces are used by musicians to make music together in "real-time" over the internet as far as real-time is possible here. The idea is to "extend" the interfaces with a word clock input for a sampling rate of 48kHz which is also going to be the GPS clock frequency.

Behind the simple technology that keeps your clock ticking.

Phase-locked loop PLL circuits exist in a wide variety of high frequency applications, from simple clock clean-up circuits, to local oscillators LOs for high performance radio communication links, and ultrafast switching frequency synthesizers in vector network analyzers VNA. This article explains some of the building blocks of phase locked loop circuits with references to each of these applications, in turn, to help guide the novice and phase locked loop expert alike in navigating part selection and the trade-offs inherent for each different application.

Software defined radio and widespread software-controlled PLL synthesis for RF has been a game changer. That was the problem [vgnotepad] faced when trying to connect a Sennheiser wireless microphone to some receivers. The solution to that is obvious — hack the transmitter! New versions of old consoles and arcade cabinets frequently make excellent fodder for clever hacks to cram as much functionality as possible into tiny modern microcontrollers. It can emulate three popular consoles, complete with ROM selection menus with menu bloops. Connect analog audio and composite video and the device is ready to go. The system provides this impressive capability with an absolute minimum of components.

Sample rate, Word Clock, PLL and more: An overview for a better understanding With the continuing change from analog to digital technology a new part of digital audio confuses more and more users: the synchronization. But which kind of synchronization? In the analog domain one can connect any device to another device, a synchronization is not necessary.

    He is surely right

  2. Bastien

    Good morning everyone! That smiled at me !!!!

    Sorry to interrupt you, I would also like to express my opinion.

  4. Brockley

    One and the same, infinite

  5. Scandy

    I used to think differently, thanks a lot for the help on this issue.
