Description : Describe the basic SHA operation with the help of its four mode specifications.

Answer : Sample-and-hold amplifier (SHA) is a unity gain amplifier with a mode control switch where the input of the amplifier is connected to a time-varying signal. A trigger pulse at the mode control switch ... but other forms, such as optical and mechanical forms, are possible. Also denoted S/H.

Description : operation of DSO with block diagram.

Answer : The input is amplified and attenuated with input amplifiers. The output of the input signal amplifiers feeds an analog to digital converter (ADC). There are numbers of ADC available. But the selection of ADC ... view the display on the CRT, the data from memory is reconstructed in analog form.

Description : What is PLL? Explain its operation with a block diagram.

Answer : PLL - A phase-locked loop or phase lock loop is a control system that generates an output signal whose phase is related to the phase of an input signal Block diagram  ... to the input frequency. The phase - locked loop goes through three states free running capture and phase lock.

Description : Describe principle of operation of Doppler type ultrasonic flow meter with diagram. 

Answer : Diagram: Working:  The flow meter consists of a crystal transducer mounted outside the pipe in which flow is to be measured. This transducer is a piezoelectric crystal which ... , so the frequency of the reflected wave is shifted to particle velocity, according to Doppler principle.

Description : What is digital storage oscilloscope (DSO)?

Answer : Digital storage oscilloscope have many advantages as compared to analogue oscilloscope. Digital storage oscilloscope uses analogue to digital converter and digital to analogue converter and also it ... oscilloscope is used for comparing waveforms and recording and it have many different uses.
