Personal Communication Example
Personal communication involves direct, usually one-on-one or small group, information exchange between individuals.
Analyzing Communication Options
Let's examine the provided options to identify the best example of personal communication:
- Television and Radio are forms of mass communication, designed to reach a large, undifferentiated audience.
- Computer can be used for personal communication (like email or chat), but it's a device that serves many functions, not solely a means of personal communication.
- Telephone service provides a direct, real-time, two-way connection between specific individuals, making it a quintessential example of personal communication.
Based on this analysis, telephone service stands out as the clearest example of a means of personal communication.
Important Questions from Communication Systems
A microphone converts
- An AM radio station transmits with a modulation frequency of $250 \text{ kHz}$, which represents $10\%$ of its carrier wave frequency. To ensure clear reception and prevent adjacent channel interference, broadcasting regulations stipulate that the entire bandwidth of any new station must not overlap with the bandwidth of an existing station. If a new license application is filed for an AM station requiring a *lower* carrier frequency than the existing station, what is the *highest* possible carrier frequency (in $\text{kHz}$) that can be allotted to this new station without causing interference?
For a generalised communication system, arrange the following in the correct sequence :
(A) Receiver
