Band Reject Filter Circuit: In this Band Reject Filter Circuit, frequencies are attenuated in the stop band and passed outside it, as shown in Fig. 15.20(b). As with band pass…
Higher Order Filter Design: Higher Order Filter Design - From the preceding discussion on filters we can conclude that in the stop band the gain of the filter changes at…
What are Passive Filters?: Passive filters are mainly networks using inductors, capacitors and resistors. The classical theory employed was based on the image parameter theory which in turn was based…
Transistor Chopper Circuit: Transistor Chopper Circuit - A single transistor used as a dynamic switch to convert low level dc signal to an ac waveform is shown in Fig. 14.34.…
Detectors Types: The Detectors Types are as follows For low frequency, the most convenient detector is the vibration galvanometer. For ordinary laboratory work at frequencies up to a few 100 Hz,…
Measurement of Capacitance using Schering Bridge: A very important bridge used for the precision measurement of capacitors and their insulating properties is the Schering Bridge Experiment. Schering Bridge basic circuit…
pH Measurement Methods: pH is defined as the negative logarithm of the active hydrogen ion. It is a measure of the acidity or alkalinity of an aqueous solution. The pH…
Frequency Selective Wave Analyzer: The Frequency Selective Wave Analyzer consists of a very narrow pass-band filter section which can be tuned to a particular frequency within the audible frequency range…
