Block Diagram of Electric Drive System: It is normal practice in control engineering to represent a control system by means of a Block Diagram of Electric Drive System, with a systematic connection of blocks in…
Interfacing of 8257 with 8085: Fig. 14.68 shows the interfacing of 8257 with 8085 in I/O mapped I/O technique. In slave mode, RD and WR signals are activated by CPU when IO/M signal is high,…
Parallel Connection of Coupled Coils: Parallel Connection of Coupled Coils - Consider two inductors with self inductances L1 and L2 connected parallel which are mutually coupled with mutual inductance M as shown in Fig. 10.20.…
Tunnel Diode Operation and Characteristics: Tunnel Diode Operation - A tunnel diode (sometimes called an Esaki diode after its inventor, Leo Esaki) is a two-terminal negative resistance device that can be employed as an amplifier,…
Output Stage of an Op Amp and its Voltage Transfer Characteristics: The output stage of an op amp is another requirement which should have very small output impedance and provide the external load current so…
Single Phase Full Wave Controlled Rectifier (or Converter): In case of Single Phase Full Wave Controlled Rectifier (or Converter) both positive and negative halves of ac supply are used and, therefore, the effective value of…
What is Current Density? By definition, the current density, denoted by the symbol J, is the current per unit area of the conducting medium i.e., where current I is the rate of flow of charge.…
Transient Response of RC Circuit: Consider a Transient Response of RC Circuit consisting of resistance and capacitance as shown in Fig. 12.6. The capacitor in the circuit is initially uncharged, and is in series with…
Data Types and Instruction Set of 8087 co-processor: The Data Types and Instruction Set of 8087 co-processor can support 7 different data types namely Three Signed Integers 16-bit (word) - range 32768 to + 32767…
Supernode Analysis: Suppose any of the branches in the network has a voltage source, then it is slightly difficult to apply nodal analysis. One way to overcome this difficulty is to apply the Supernode Analysis.…
