Theory and Terminology Note Frequency Hop Spread Spectrum vs. Direct Sequence Spread Spectrum Direct Sequence Spread Spectrum (DSSS): The DSSS encoder spreads the data across a broad range of frequencies using a mathematical key. The receiver uses the same key to decode the data. 1 As a general rule‚ FHSS can resist interference from spurious RF signals ten times better than DSSS. 928 MHz The frequency range is divided into channels. The data is transmitted on these randomly

1. List three key components involved in the communication process. • Sender (encoder). • Channel (Message). • Receiver (Decoder). 2. Identify three key characteristics of effective communication and briefly explain their impact on the communication process. Openness is a key characteristic of communication‚ as by listening with an open mind and showing genuine interest‚ the relationship and trust between the client and counsellor grows. Openness with body language is also important

In “Helping Students Use Textual Sources Persuasively‚” Margaret Kantz talks about how individuals should read texts to write a synthesis essay. To write a synthesis essay‚ one should be able to come up with an argument and find information from other sources‚ and use them as proofs to back up the argument. First‚ Kantz talks about the mistakes that students usually make when they write this essay. For instance‚ Shirley made a mistake by reading a repeating and telling the story instead of creating

Decoding refers to the act of understanding messages-for example‚ listening or reading. Thus‚ speakers and writers are called encoders and listeners and readers decoders. • • Competence Competence includes knowing how to adjust your communication according to the context of the interaction‚ the person with whom you are interacting.

Vehicle Density based Traffic Signal Light There has been a need to automatically control things from a distance depending on a certain timing logic. In recent past there had been many instances of accidents on the roads‚ at the crossings near the colonies for the fact that there were no streetlights ON in the night when the visibility of the driver is poor. Even at the junctions such as T-junction‚ Y-junctions or circle we should be able to distribute the traffic in such

Random number tables have been used in statistics for tasks such as selected random samples. This was much more effective than manually selecting the random samples (with dice‚ cards‚ etc.). Nowadays‚ tables of random numbers have been replaced by computational random number generators. Tables of random numbers have the desired properties no matter how chosen from the table: by row‚ column‚ diagonal or irregularly. The first such table was published by a student of Karl Pearson’s in 1927‚ and
