Intermediate Frequency Amplifier: Choice of frequency: The Intermediate Frequency Amplifier (IF) of a receiving system is usually a compromise, since there are reasons why it should be neither low nor high, nor in a certain…
Interlocking Components in Electrical Drives: Sensing of signals required for speed and current control loops. Sequencing and interlocking operations are explained in the previous section, whereas this section discusses components used in interlocking and sequencing…
Interference of Power Lines Interview Questions and Answers: 1. How do power lines cause interference with neighbouring communication lines ? Ans. The transmission lines transmit bulk power at relatively higher voltages and, therefore, these lines…
Interference of Electromagnetic Waves: Interference of Electromagnetic Waves occurs when two waves that left one source and travelled by different paths arrive at a point. This happens very often in high-frequency sky-wave propagation and in…
Interference in Telecommunication Circuit in Electric Traction: In all traction systems track is used as a return path for the current. Some part of the current flows through the track and the remaining portion of…
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,…
Interfacing Dip Switch: A series of tiny switches built into circuit board and the housing for which has a same shape as chip are known as DIP switches. The Fig. 15.23 shows the Interfacing Dip…
Interfacing 8259 with 8085: Fig. 14.72 shows Interfacing 8259 with 8085 microprocessor system. Addressing of 8259A : The 74LS138 address decoder will assert the CS input of the 8259A when an I/O base address is…
Interfacing 8251 with 8085: Fig. 14.44 shows the Interfacing 8251 with 8085 in I/O mapped I/O technique. Here, RD and WR signals are activated by CPU when IO/M signal is high, indicating I/O bus cycle.…
Interconnection of Two Port Network: Various types of Interconnection of Two Port Network such as series connection of two ports, parallel connection of two ports, cascade connection of two ports etc. Series Connection of Two…
