What are the disadvantages of face to face communication?

Face-to-face conversation is not effective in communicating with large audiences. It is very hard to get a message across to huge gatherings. Even though the narrator is addressing them face-to-face, the essential personal touch is missing. In the deficiency of reasonable feedback, his speech lapse into a monologue.

Which one of the following are the disadvantages of PCM?

Following are the drawbacks or disadvantages of PCM: ?Overload appears when modulating signal changes between samplings, by an amount greater than the size of the step. ?Large bandwidth is required for transmission. ?Noise and crosstalk leaves low but rises attenuation.

Which one is the disadvantage of digital communication * easy processing easy multiplexing easy signaling increased bandwidth?

Explanation: Digital communication is a very reliable communication. It is easy for multiplexing, easy for signalling and processing etc. __________________ is necessary for digital communication. This is considered as a disadvantage of digital communication.

Is the disadvantage of digital signal processing?

Drawbacks or disadvantages of DSP
?The use of DSP requires anti-aliasing filter before ADC and re-construction filter after DAC. Moreover it requires ADC and DAC modules.This requires training on the DSP in order to program for various applications. Hence only highly skilled engineers can only program the device.
