What is Inductor in Electronics? An inductor has been defined as a physical device which is capable of storing energy by virtue of a current flowing through it. An Inductor…
Chebyshev Approximation: Chebyshev Approximation - In the earlier section, we have studied that the Butterworth approximation is the best at ω = 0. But as we move towards cut-off frequency,…
Butterworth Approximation: Butterworth Approximation - In low-pass filter design, we have to assume that all transmission zeros of the system function are at infinity. Then the magnitude function in general…
Monochrome Television Receiver Block Diagram: Monochrome Television Receiver Block Diagram as shown in Figure 17-9, TV receivers use the superheterodyne principle. There is extensive pulse circuitry, to ensure that the…
Measurement of Information in Communication System: Having said what information is not (it is not meaning), we now state specifically what information is. Accordingly, information is defined as the choice…
Impedance Matching and Tuning in Waveguide: We know that suitably chosen series or parallel pieces of transmission line had properties which made them useful for providing resistive or reactive impedances.…
Quarter Wavelength Transmission Line: Sections of transmission lines that are exactly a Quarter Wavelength Transmission Line or Half Wavelength Transmission Line long have important impedance-transforming properties, and are often used…
Delayed Automatic Gain Control: Delayed Automatic Gain Control: Simple AGC is clearly an improvement on no AGC at all, in that the gain of the receiver is reduced for strong…
