This white paper raises some fundamental issues the design engineer should address before deciding upon a communication approach for a wireless network. As no universal wireless network solution exists, it should be custom tailored to suit the application demands. Defining your application communica ...
Analog Inputs and Outputs in an S7 PLC are represented in the PLC as a 16-bit integer. Over
the nominal span of the analog input or output, the value of this integer will range between -
27648 and +27648. However, it is easier to use the analog values if they are scaled to the
same units and ra ...
Designing read/write device (RWD) units for industrial RF-Identification
applications is strongly facilitated by the NXP Semiconductors HITAG
Reader Chip HTRC110. All needed function blocks, like the antenna
driver, modulator demodulator and antenna diagnosis unit, are integrated
in the HTRC11 ...
针对煤矿井下调度及紧急救援系统的需求，以DTMF编解码模块为核心，设计了具有自动拨号功能的新型电话系统。该系统利用MT8880对DTMF信号的编解码功能实现一键拨号和远程设置，通过检测振铃和忙音信号，完成自动摘机和挂机过程，配合AGC等外围电路达到话音清晰流畅的效果。
