How do you calculate channel capacity when SNR is present? Hence, the channel capacity is directly proportional to the power of the signal, as SNR = (Power of signal) / (power of noise). so for example a signal-to-noise ratio of 1000 is commonly expressed as: 10 * log10(1000) = 30 dB. What is channel capacity? […]

Can Exercise change your face shape? Redistribution of fat: Regular exercise can help to move fat deposits within your body. This can make the face appear more toned and full.

Can the brain run out of space? In one sense, yes. Memory depends on forming new neural connections, and the brain has a finite number of neurones and a limited space in which to add more connections between them. Yet in another sense a healthy brain can never stop learning. There is really no such […]

How self-driving cars will impact society?
