Electronics Interview Questions -I --------------------------------------------- 1.What is meant by filter? What are the different types of filters? A:The output of the rectifier pulsating in nature, it consists of a desired DC component of voltage and unwanted ripple components. These ripple components are removed by placing filter circuit at the output of the rectifier. Types of filters: 1. capacitor filter 2. series inductor filter 3. LC filters of following two types (a)capacitance input filter (b)inductance unput filter 4.RC filters. 2.What is a sequential circuit and what is a combinational circuit?Is there any difference between them? If yes what is it? A:Combinational circuit are those whose output depends only upon the present inputs but in sequential circuit the output depends upon both present and past inputs. that is the difference. 3. What type of architecture is used in 8085 microprocessor? A: NTEL 8085 is a 8-bit microprocessor. Its based on Von-Neumann architecture in which the data and instructions are in the same memory space without any distinction between them. Data line: 8-bits--Can process 8-bits of data at a time. Address line: 16-bits--Can address upto 2^16(64KB) of address space. 4. What are edge triggered flip flop and level triggered flip flop? How do they differ from one another? A:level trigger ff work only the level of the signal either high(1) or low(0) but edge trigger work on the either rising edge or talling edge 5. What is the main application of scr in electronic field as well as in software field? A: A silicon-controlled rectifier (or semiconductor-controlled rectifier) is a four-layer solid state current controlling device. The name silicon controlled rectifier or SCR is General Electrics trade name for a type of thyristor.
