Provide (2) 150 words response with a minimum of 1 APA references for RESPONSES 1 AND 2 below. Response provided should further discuss the subject or provide more insight. To further understand the response, below is the discussion post thats discusses the responses.
DISCUSSION 1:
A system that produces radio frequencies for communication requires multiple components. Some of those radio components include amplifiers, antennas, filters, and mixers. A version of all of these hardware pieces are found in most radio systems. A radio frequency amplifiers is used to convert low powered radio frequency signals into higher powered signals. Antennas are used to convert radio frequency signals from the transmitter into electromagnetic waves which are delivered through the air or empty space. Filters are used to block or accept radio frequency signals by setting thresholds. Low pass filters set maximum frequency thresholds. In these instances any signal that is below the set maximum threshold is allowed to pass through the filter. On the other end a high pass filter is used to set minimum frequency thresholds, and only allows signals to pass through that are above the set minimum. A bandpass filter is a combination of the previous two filter. Bandpass filters create a bandpass which allow for both a minimum and maximum threshold setting. Finally mixers are used to combine two signal inputs and then produce a single output.
Overall amplifiers, antennas, filters, and mixers are necessary and required hardware for any radio system. However beyond these radio components there are other design considerations that should be taken into account when a radio system is created. One of those considerations is the radio frequency being used. Being that there are a limited number of frequencies available, it is best to try and conserve them as much as possible. An example of frequency conservation cold be a multiple users using the same channel.
DISCUSSION 2:
Several elements make up a radio system to function, such as filters, mixers, amplifiers, and antennas.
A filter cleans out the noise by blocking out all of the radio frequency (RF) signals that are not wantedsurrounded by RF signals generated by transmission equipment like cell phones, satellites, radio, and tv transmitters. Filters are like gatekeepers that filter RF signals by either allowing them or blocking them. There are three types of filters one is a low-pass, bandpass, and a high-pass.
A mixer is a component that combines tow inputs to create a single output. (Olenewa, 2013, p. 474) A blender will determine the difference in either the lowest or highest between the input of frequencies.
An amplifier is a component that increases a signals intensity. (Olenewa, 2013, p. 468) The amp is a critical component as it can increase the power of the signals received, and while RF signals travel through the air tend to weaken.
An antenna is a copper wire, rod, or similar device that has one end up in the air and the other end connected to the ground through a receiver. (Olenewa, 2013, p. 468) An antenna is imperative for electromagnetic waves to be transmitted or received.
