This process is called rectification. Tell me a bit about yourself. There are a number of things to consider, and they are as follows. Advantages of negative feedback over positive feedback. A repeater is an electronic device that receives a signal and retransmits it at a higher level and/or higher power, or onto the other side of an obstruction, so that the signal can cover longer distances without degradation. For Analog modulation–AM, SSB, FM, PM and SM this statement is an outcome of Attenuation is usually measured in units of decibels per unit length of medium (dB/cm, dB/km, etc) and is represented by the attenuation coefficient of the medium in question.

Walk-in Interview for Assistant Professor on 10.08.2013 at 10.00 am GGSIP University invites eligible and willing candidates for the post of Assistant Professors as per the following details, purely on Contract basis for a period of six months or till the positions are filled on regular basis, whichever is … AM-Amplitude modulation is a type of modulation where the amplitude of the carrier signal is varied in accordance with the information bearing signal. (a) it has extremely high input impedance,much higher than even its open loop input impedance We know that they might not be the only questions asked in the interview but they are generic and most interviewers ask these questions in the interview. (a) forward ON- state characteristics When you answer interview questions about something you’ve done it’s best to use the STAR method (situation, task, action, result). Example for –ve feedback is —Amplifiers 1. What is modulation? … (c)t = RC (d) none of these, 17. in the astable mode of operation of IC 555, the timing capacitor always charges between Difference between CDMA and GSM. ), 7 of the Best Situational Interview Questions. (c) a higher power loss (d) a peaked response, 85.lower the thermal resistances (junction-to-case-to-ambient) of a bipolar transistor, 87. the characteristic impedance of a certain transmission line section is 75 ohms. The types of questions covered are general, behavioral, situational, discipline and experience based. (c) decibels (d) volts per microvolt, 14. a given opamp has an open loop gain of 110dB and a CMRR rating of 106dB. (c) monopulse radar (d) secondary surveillance radar, 89. the radar that has a higher range resolution and that makes use of matched filter design is And for +ve feedback is – Oscillators.
