A digital-to-analog converter (DAC) is a very common device with capabilities far beyond the range of level settings, it also extends to communication, video, audio, potentiometer and alternative variable resistors, signal synthesis, and many other applications.

Abstract: The successive approximation register type (SAR) ADC occupies most of the medium to high resolution ADC market. The sar adc has a maximum sampling rate of 5 MSPs and a resolution of 8 to 18 bits. The SAR architecture allows high-performance, low-power ADC to use small-size packages and is suitable for systems with strict size requirements.
This article describes how sar adc works and converts input signals using a binary search algorithm. This article also provides the core architectur
assistant first converts the objects (including tables, primary keys, foreign keys, and constraints) in access to the objects in SQL azure, create these objects in the SQL azure database, and then convert all data rows in the table and load them into the SQL azure database. For the process of converting objects, the migration assistant generates a detailed report. We can click the report button to browse.

9.4 Dedicated Administrator Connection9.4.1 The concept of dedicated administrator connectionsWhen SQL Server no longer responds to a standard connection request, the administrator needs to perform a diagnostic query and resolve the problem, but the SQL Server cannot be accessed through a normal connection request at this time.SQL Server provides a dedicated administrator connection (dedicated Administrator Connection, referred to as a DAC). Even if t
ObjectiveThe function of the digital-to-analog converter DAC is much smaller than the timer Tim, the serial port Usart, and so on, which is why the internal integrated DAC module is not so many. However, in a project that requires the use of a digital-to-analog conversion function, this DAC module can basically replace the plug-in

SQL Server 2005 provides an administrator with a special diagnostic connection for use when it is not possible to establish a standard connection with the server. Even when SQL Server does not respond to standard connection requests, administrators can use this connection to access SQL Server to perform diagnostic queries and resolve problems. The command line Interface (SQLCMD) provides and supports this dedicated administrator conne

Editor's Note: This is a guest post from James Morris, the Linux kernel security subsystem maintainer and manager of the mainline Linux kernel development team at oracle.
In this article, we'll take a high-level look at the security features of the Linux kernel. We'll start with a brief overview of traditional UNIX security, andRationale for extending that for Linux, then we'll discuss the Linux security

The ac97 interface or I2S or PCM Interface can connect the CPU and CODEC (wm9714/alc5620/alc5621), and configure the format: the PCM Interface must be configured with the sampling rate, number of sampling digits, number of channels, and transmission format. The I2S interface must be configured with the sampling rate, number of sampling digits, number of channels, and alignment mode. The ac97 interface is flexible, it can be considered that t
