Edit

8 KHz as the sampling frequency will be double the maximum frequency component for no aliasing effect, as per the nyquist theorm. as the maximum frequency allowed by the filter is just 4khz. so the sampling frequency is 8KHz

In my previuos job I faced difficulty with customer critised me for the product. I tried to conviced the policy and about the product with polietly altimatly he agreed with my thought.

I was woking with non- profit organization at that time i phoned for fundrising. Really, I never forget that day gentleman told me that your voice is very soft and he impressed with my presentation. That was my one of the best experince at Call Centre

In a baseband transmission, the entire bandwidth of the cable is consumed by a single signal. In broadband transmission, signals are sent on multiple frequencies, allowing multiple signals to be sent simultaneously.

Also

Baseband Signalling:

1)Uses digital signalling

2)No frequency-division multiplexing

3)Bi-directional transmission

4)Signal travels over short distances

Broadband Signalling:

1)Uses analog signalling

2)Unidirectional transmission

3)Frequency-division multiplexing is possible

4)Signal can travel over long distances before being attenuated

Modulation is the method by which a high-frequency digital signal is grafted onto a lower-frequency analog wave, so that digital packets are able to ride piggyback on the analog airwave.
