Electronic Engineering is considered to be one of the most favored streams among students. Before you begin with the question and answer, let’s learn a bit about the electrical discipline. This field will help you to learn the devices, signals, and inputs. According to the analog assignment help experts, if you want to master Electronic Engineering, then you must have a good knowledge of the basics of the subject. Let’s begin with the questions with effective answers.
Q) What is Analog Modulation?
A) Modulation is a message which is carried by a signal to pass on further so that it could set up good communication through high frequency. If the quality and the attribute of the signals changes, then the message which is carried out, is also affected by it. That is why it is important to send the message on a high-frequency level, which is also known as a carrier signal so that it can move to extended places without being affected by any exterior disruptions. The whole process is called modulation.
Q) What Is the Need and Advantages of Modulation?
A) The baseband signals are not capable of direct transmission, which is why to increase the strength of the signal, modulation is necessary. It has also removed the need for wires in the communication structure. It also helps in preventing the signals from mixing.
Advantages: - The antennas that were used earlier were huge; it is because of modulation that the range is not limited. Other advantages are, the range of communication has expanded, the standard of the reception is upgraded.
Q) What is the Difference Between PM and FM.
A) Frequency modulation is also known as a carrier wave. In this, the frequency changes according to the modulating signal value Amplitude Modulation is a commonly used mode in electronic communication to pass on the message through radio waves.
Q) What Is a Noise Figure?
A) Noise figure is a way- by which you can measure the noise performance of circuit block, amplifier, mixer, and many others. It is also used in RF circuit design to know if there is any new radio development.
Q) Define the Deviation Ratio and Its Formula?
A) Deviation ratio is considered to be the most terrible modulation index case, which is similar to the topmost peak of the frequency deviation, which is then divided by the greatest modulation signal frequency. The formula of deviation ratio is m = Max frequency deviation, which is divided by Max modulation frequency.
Q) What Are Carson’s Rule and Its Formula.
A) Carson’s bandwidth rule explains the estimated bandwidth which is needed for the communication process. It is used as an element for the carrier signal which is frequency modulated by multiple frequencies and not by just a single frequency. Its formula is B =2(f + fm) Hz.
Conclusion!!!
The analog assignment help experts have provided some excellent question with answers for you that will help you learn some basics about the subject if you are a fresher.
