    Abstract: A monitoring camera has a base, a camera module and a casing. The base has a parapet formed on the base. The parapet has a memory slot and at least one pair of guide slots formed oppositely on the parapet. Each guide slot has a notch extending toward the bottom of the parapet. The casing corresponds to and covers the parapet and has at least one pair of guide protrusions formed on the casing. The guide protrusions respectively engage corresponding guide slots. When unscrewing the casing, the guide protrusions will correspondingly move and be mounted in the notches and the memory slot is accessible. Therefore, the casing need not to be completely detached from the base to allow a removable memory to be installed or removed easily.

    Abstract: A device and method for measuring the jitters of phase locked loop signals. A phase lead or phase lag relationship between an input signal and an output signal of a phase locked loop is found. According to the phase relationship and using multiplexers, a first phase difference signal and a second phase difference signal are re-routed to a subtraction unit and produces a jitter-level output signal. The jitter-level output signal represents the absolute value of the difference of pulse width between the first phase difference signal and the second phase difference signal.
