The SENT protocol is a one-way, asynchronous voltage interface which requires three wires: a signal line (low state < 0.5 V, high state > 4.1 V), a supply voltage line (5 V) and a ground line. SENT uses pulse-width modulation to encode four bits (one nibble) per symbol.
Cutaway view of an LVDT. Current is driven through the primary coil at A, causing an induction current to be generated through the secondary coils at B.. The linear variable differential transformer (LVDT) – also called linear variable displacement transformer, [1] linear variable displacement transducer, [2] or simply differential transformer [3] – is a type of electrical transformer [4 ...
The 2N7000 is housed in a TO92 package, with lead 1 connected as the source, lead 2 as the gate, and lead 3 as the drain. The BS170 has the source and drain leads interchanged. The 2N7002 variant is packaged in a TO-236 surface-mount package. The 2N7000 is an N-channel, enhancement-mode MOSFET used for low-power switching applications. [1]
If push–pull output was mistakenly used instead, the active device attempting to set the line voltage low would be in competition with the other devices attempting to set the line voltage high, which would result in unpredictable output and heat. SCSI-1 devices use open collector for electrical signaling. [9] SCSI-2 and SCSI-3 may use EIA-485.
IEEE 1451 is a set of smart transducer interface standards developed by the Institute of Electrical and Electronics Engineers (IEEE) Instrumentation and Measurement Society's Sensor Technology Technical Committee describing a set of open, common, network-independent communication interfaces for connecting transducers (sensors or actuators) to microprocessors, instrumentation systems, and ...
Low-voltage positive emitter-coupled logic (LVPECL) is a power-optimized version of PECL, using a positive 3.3 V instead of 5 V supply. PECL and LVPECL are differential-signaling systems and are mainly used in high-speed and clock-distribution circuits. A common misconception is that PECL devices are slightly different from ECL devices.
A line impedance stabilization network (LISN) [1] is a device used in conducted and radiated radio-frequency emission and susceptibility tests, as specified in various electromagnetic compatibility (EMC)/EMI test standards (e.g., by CISPR, International Electrotechnical Commission, CENELEC, U.S. Federal Communications Commission, MIL-STD, DO-160 Sections 20-21-22).
Figure 3: PNP version of the emitter-follower circuit, all polarities are reversed. A small voltage change on the input terminal will be replicated at the output (depending slightly on the transistor's gain and the value of the load resistance; see gain formula below). This circuit is useful because it has a large input impedance
