Measuring Amplitude Modulation Using CRO: The CRO is widely used as an Measuring Amplitude Modulation. It presents the waveform for visual monitoring and is fairly accurate in measurements of modulation…
Audio Amplifier Frequency Response: The Audio Amplifier Frequency Response is essential for filters, couplings circuits, amplifier stages and overall audio circuits. An amplifier stage is used as an example. A…
FIR 1-D Digital Filter Design (The Window Method): We describe the Fourier series technique as the first design method of 1-D FIR digital filters [Eq. (15.83)]. In this Digital Filter…
Introduction to Digital Filtering: It has been seen that control of the band width of a circuit or signal is of paramount importance in optimizing the measurement of a signal.…
What is a Filter Circuit?: A network designed to attenuate certain frequencies but pass others without attenuation is called a filter. A filter circuit thus possesses at least one pass…
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.…
Differential Instrumentation Amplifier Transducer Bridge: Figure 14.25 shows a simplified circuit of a Differential Instrumentation Amplifier Transducer Bridge. In this circuit a resistive transducer (whose resistance changes as a function…
