When a PLL is being used as a frequency synthesizer, the output is taken from 
When an oscilloscope has a low bandwidth, which type of signals CANNOT be displayed correctly?
How should be the output of a transducer?
What is the name of a device that converts sound waves to electrical waves?
The following items consist of two statements, one labeled as “Assertion (A)” and the other labeled as the “Reason (R)”. You are to examine the two statements carefully and decide if the Assertion (A) and the Reason (R) are individually true and if so whether the reason is a correct explanation of the assertion. Select your answer to these items using the codes given below and mark your answer accordingly. Assertion (A): A sphygmomanometer is always used in conjunction with a means to determine at what pressure, blood flow is just starting, and at what pressure it is unimpeded. Reason (R): Manual sphygmomanometers are used in conjunction with a stethoscope.
For display of a sine wave in a CRO, what waveform is applied ot the horizontal plates?
Which of the following instruments have large scales for easy reading?
Consider the following statements for deflection and null type instruments: 1. Deflection type of instruments are more accurate than null type of instruments. 2. Deflection type of instruments can be highly sensitive as compared with the null type of instruments. 3. Null type of instruments are more suitable for measurements under dynamic conditions than deflection type of instruments. Which of the above statements are not correct?
