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,…
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…
Classification of Communication: There are two basic classification of communication systems, baseband systems and passband systems. In baseband systems, the signal is transmitted without modifying the frequency content. A simple…
