, the crystal oscillator is equivalent to an inductor, as long as the two ends of the crystal oscillator are connected in parallel with an appropriate capacitor, it will constitute a parallel resonance circuit. This parallel resonant circuit can be added to a negative feedback circuit to form a sine wave oscillator circuit. Because the frequency range of the crystal oscillator equivalent to inductance is very narrow, even if the parameters of other components change greatly, the frequency of thi

Intent:Provides a consistent interface for a group of interfaces in the subsystem. The facade mode defines a high-level interface, which makes the subsystem easier to use. Structure: Example: Suppose you have a killer home theater system that includes a DVD player, a projector, an automatic screen, and surround sound. So what do you need to do when you want to watch a DVD )? 1. Dim the light; 2. Drop the screen; 3. Open the projector; 4. Switch the projector input to the DVD;

(facade), which aims to simplify the interface. The appearance class does not encapsulate subsystems, but provides a simplified set interface. This is actually a simple concept. It not only simplifies the interface, but also decouples the customer from the component subsystem. Both the appearance and the adapter can wrap multiple classes, but the appearance is intended to simplify the interface, and the adapter's intention is to convert the interface into different interfaces. The book provides

The theoretical output impedance of the operational amplifier is zero, which is unlikely to be a matching problem.The general Op Amplifier has little driving power. Check its manual to show the load resistance value of a typical application, which is usually in the order of KB. If your probe impedance is smaller than it, the driver capability is insufficient, and the power

Wireless Bridge Mode Point-to-Point wireless bridges can be used to connect two networks located in different locations. They generally consist of a pair of bridges and a pair of antennas. The point-to-point Wireless Bridge to the bridge should be set to the same channel, AboveCable ACAP2020-11/B Support synchronous channel function, only need to change one channel, another convenience will be automatically changed to the corresponding channel. AboveCable provides a two-way power

output meaning this they can handle voltages from VSS to VDD. There is numerous such parts like the MC33201.There is a look at this current limiter circuit in Wikipedia [2]. Voltage over the sense resistor are kept equal to Voltage over Z-diode. Okay, there is no z-diodes of really low voltage. Since the amplifier have high input impedance we can use a voltage regulator and simply reduce the voltage using a voltage Divider.One point still to notice a

Although the advantages of a fully digital feedback path is impressive-including elimination of temperature and comp Onent-tolerance problems in the Error-amplifier/loop filter, and the ability to switch the response characteristics on the Fly-limitations still exist to the this design. These limitations is primarily in the pulse-frequency restrictions imposed by the purely digital PWM. (Remember a PWM peripheral with a resolution of 8 bits

Hand-taught network cable, according to different needs, make practical network cable Main Line (Standard 568b): the two ends of the line Order is the same, the line order is: White orange, orange, white green, blue, white blue, green, white brown, brown.Reverse line ( 568a ): One end is the line sequence of the positive line, and the other end is: white green, green, white orange, blue, white blue, orange, white brown, brown.PC-PC: reverse linePC-HUB: Main LineH

other side. That is, the sender of one end is received by the other side and received by the other side. 100baset is connected to a twisted pair. The 100 Mbit/s EIA/TIA 568b is used as the standard specification.The procedure is as follows:Step 1: Use the oblique port to cut down the required twisted pair length, at least 0.6 meters, up to 100 meters. Then, remove the outer skin of the twisted pair (which can be used to cut anything) with 2-

With the rapid development of computer technology and the demand for fast communication, the demand for network speed is increasing. As a network communication platform, the bandwidth of the Integrated Wiring System is also increasing. The Integrated Wiring System has grown from Category 5 to Category 5. Currently, Category 6 and Category 7 are gradually accepted by users. After nearly four years and more than a dozen revisions, in June this year, the ANSI/T
