Color TV Transmission: Having discussed the manner of indicating luminance and the two components of chrominance in Color TV Transmission, it is now necessary to investigate how they may be,…
Color TV Transmission and Reception: If color TV had come before monochrome TV, the system would be far simpler than it actually is now. Since only the three additive primary…
Monochrome TV Transmitter - Block Diagram and its Workings: The term monochrome stands for black and white. Thus a monochrome TV system does not process variations of colour in a…
TV Video Waveform: Blanking - TV Video Waveform voltage is limited to certain amplitude limits. Thus, for example, the white level corresponds to 12.5 percent (±2.5 percent) modulation of the…
Fundamentals of Transmission Lines: Fundamentals of Transmission Lines (in the context of this book) are considered to be impedance-matching circuits designed to deliver power (RF) from the transmitter to the antenna,…
Measurement of Power Transmission Lines: When power is applied to Measurement of Power Transmission Lines, the source to load impedance must be matched in its characteristics impedance (Z0). The impedance…
Electronics Engineering Multiple Choice Questions and Answers (MCQs) Part 4: 150. In phase modulation, phase deviation is proportional to (a) carrier amplitude. (b) carrier phase. (c) message signal. (d) message…
Base Modulation Circuit Working Principle: The circuit for base modulation is shown in Fig. 22.28. The carrier signal from a crystal oscillator is coupled to the base terminal of the…
