Sub-transmission substations are located near to high load concentrations, usually in urban areas.
a sub system is little systems that are part of a bigger system
One example of a system and sub system in system analysis and design is an organization (system) with interrelated department (sub system). Another example would be a computer (system) and all of its components (subsystem).
In many cases, the cost of the transmission medium is large compared to the cost of a single transmitter/receiver pair or a modulator/demodulator pair. If there is spare bandwidth, then the incremental cost of the transmission can be negligible. The new station pair is simply added to an unused sub channel. If there is no unused sub channel it may be possible to re divide the existing sub channels creating more sub channels with less bandwidth. If, on the other hand a new pair causes a complete new line to be added then the incremental cost if large indeed.
IR transmission type of transmission is used in television system .
Yes, you do.
The relationship between a system and sub-system, is that they are both a part of each other. If a circle is the system, the different pieces inside of this circle are the sub-systems. You cannot have one without the other.
The definition of a transmission system is a system that transmits a signal from one place to another place.
it's consist of big system and that system we sub divided into sub systysem called a distrbuited system. an example of this is a scada system that have one main control system and through that system we distrbute the system to the site that we have which called a distrbuted system .
We can use DC too for the transmission system. Refer HVDC transmission system.
equinoctial system of coordinates
A failure in the transmission.
