Euler loop problems:Is it possible to go from one point to the next, and each side just goes back to the starting point?The Euler circuit of the non-direction graph:If each vertex in the graph has an even number of degrees, you can draw a line from the starting point to the terminating point, which is the Euler loop of the graph without direction;The Euler circuit of the graph:If the degree of each vertex of the graph is equal to the degree of entry, then a line can be drawn from the starting po

1. Non-retention Ram/register:If the use of Ram/register itself in the Power-down state can not save its own state, then make sure that they will be in the power-up when the reset.2. Output signal of Power-down part circuit in chip:Power-down some of the output signals of the circuit can be used by other power-on parts of the circuit, then these signals must be processed. Avoid the X-value transmission to the power-on part of the circuit.There are three kinds of processing methods: latch (the va

Codeforces 91C Ski Base addition edge Euler's number of circuits Question: Returns n vertices and m undirected edges. Start to merge without edges, add an edge each time, and then output the number of Euler loop. Ideas: We will count the number of ski bases including the base consisted of empty subset of edges (before printing just subtract one ). in the beginning the number of bases is equal to 1. if we connect vertexes in the same connected compon

this point we need to reduce the 15v voltage to 12VNow it is possible to analyze a situation if the temperature switch is connected directly to the power device.The answer is no, for the following reasons.Temperature sensor switch through the current is limited, so the temperature switch can not be directly connected to the power device, the temperature switch can only provide signals.Now we're going to consider a device transistor.When the transistor's base-level current IB>1MA transistor is i

→ 1:1002 → t:100The problem is that there is a ring in the original. Loop flow, and we're not using it, causing the flow to increase.Workaround: Don't add t first → s edge right for infinite side, ask SS → The maximum flow of the TT, assuming that there is no flow full then add t → s edge right for infinite edge, and then the maximum flow to get the remorse edge s → T is the minimum flow of the original problem. Ps:1: The edges in the network stream are forward. Be sure to pay attention to

violates the cross-clock domain processing method.Riple The glitch filter circuit is mainly used to filter out the diow-signal falling edge glitch, which has no effect on the rising edge Burr. The rising edge burr does not cause data errors in this circuit.Riple When using this glitch filter circuit, you must consider the proportional relationship between the level length of the filtered signal and the synchronization clock period. In this example, if the 20 NS clock is used for filtering

data areas, and intersection lines are data-changing points of time.The longitudinal longest dashed line is the reference point for data and control signal acquisition, i.e., the falling edge sampling of the HstrobeIn the case of output readout data, both the shadow and non-shaded areas are read-out data time periods, but the shaded area represents the unstable period, and the non-shaded area represents the stable validity period of the data, which can be sampled to read valid data at the momen

My previous question stopped for a long time because-I went to write a book.ObjectiveI started working in March 2012 and now I'm six years away. For the past six years, I have never known anything about SQL Server, only the simplest C # programmers have started, stepping back from a nameless outsourcing company to the middle of a larger financial institution, with wages rising to nearly four times times the size of a new job. In the process of struggle, I also go a lot of detours, once very depr
