Comparison of stepper motor with DC servo motor :


sr. No.
Stepper motors
DC servo motor
1.
Control winding is not present.
Control wingding              is
present
2.
Stepping              rate        is
governed by frequency of switching and not by supply voltage.
Does not rotate in steps.
3.
Number of steps can be precisely controlled by controlling the number of pulses.
DC servo motor gives continuous rotation.
4.
Brushes are absent.
Brushes are present
5.
Maintenance is low
High maintenance
6.
Due        to            load/no                load
conditions no change in running current.

Multiplexing and Multiple Access

Multiplexing And Multiple Access : Digital Communications Difference between Multiplexing and Multiple Access: Sr.No. Multiplexing Multiple Access 1 “In telecommunications and  computer networks, multiplexing is a process where multiple analog  message signals or digital data  streams are combined into one   signal over a shared medium.” “In telecommunications and computer networks, a channel access method or multiple access  method allows several terminals connected to the same multipoint physical medium to transmit over it and to share its capacity.” 2 The multiplexed signal is transmitted  over a communication channel,  which may be a physical transmission medium. A channel-access scheme is  based on a multiplex method  that allows several data streams  or signals to share the...

Difference in between Time division multiplexing (TDM) and Frequency division multiplexing (FDM)

Difference in between TDM and FDM: This page on FDM versus TDM describes  difference between FDM and TDM multiplexing . FDM is the short form of frequency division multiplexing and TDM is the short form of time division multiplexing. In FDM each signal is modulated onto different unique RF carrier frequency and all carrier frequencies are separated significantly so that bandwidth of the signals do not overlap in frequency domain. Figure: Difference in between TDM and FDM
