radiated efficiently because of the antenna size. The high energy signal waves (1GHz − 1000 GHz) penetrate the ionosphere. 10 MHz frequencies get reflected easily from the ionosphere. Hence‚ signal waves of such frequencies are suitable for beyond-the-horizon communication. Question 15.2: * Answer (d) Answer: Space waves Owing to its high frequency‚ an ultra high frequency (UHF) wave can neither travel along the trajectory of the ground nor can it get reflected by the ionosphere. The signals having

CHAPTER 1 INTRODUCTION 1.1 Introduction Condition Monitoring is a technique of monitoring the operating characteristics of plants‚ equipment or systems in such a way that changes in the monitored characteristics can be used to predict the need for maintenance before a serious deterioration or breakdown occurs. It aims at detecting condition leading to catastrophic breakdown and loss of service‚ reducing maintenance overhauls‚ fine tuning of operating equipment‚ increasing production and operating

Introduction What is HFT? While there is no definite answer to what "high frequency" might be‚ it has been generally accepted that they are the type of trades automated by machines using proprietary algorithms and trade at very high speeds‚ often executing at least a few trades in under a second. HFT strategies can be broadly categorized into 4 groups: Liquidity Providence: Rebate Trading‚ Automated Market Trading. Pricing Inefficiency Arbitrage: Scalping‚ Latency Arbitrage‚ Statistical Arbitrage

ABSTRACT: The RF relay control‚ as the name suggests‚ operates at Radio Frequency. The corresponding frequency range varies between 30 kHz & 300 GHz. In this RF system‚ the digital data is represented as variations in the amplitude of carrier wave. This kind of modulation is known as Amplitude Shift Keying (ASK). Transmission through RF is better than IR (infrared) because of many reasons. Firstly‚ signals through RF can travel through larger distances making it suitable
