If the time period is 100 msecond, what is the frequency in kilohertz? if a sinusoidal signal is off-set to one-sixth of a cycle, with respect to time 0, what is phase difference in degrees? if the band pass filter has lower cut off frequency of 2khz and upper cut off frequency is 20 khz, what is the bandwidth of this band pass filter? a tv screen has 525 (vertical pixels) per line and 70o0 (horizontal pixels) per line. if display scans 30 times odd number of lines and 30 times even number of lines, and each pixel is represented by 24 bits, what is the bit rate to display one screen display? digital signal has 16 different levels, how many bits may be used to represent 16 different levels? text display has 24 lines per display page. each line has 80 characters. each character is represented by 8-bits. what is the bit rate to display one page? give answer in mbps. a signal strength of 10 watts is transmitted by an antenna. signal received is 7 watts. what is power ratio in db? is it signal gain or 3 4 5 6 7 8 attenuation? 9 input of an amplifier is 10 mwatts and the output of the amplifier is 0.1 watts. what is the amplifier gain or attenuation in db? 10 noiseless channel has bandwidth of 3000 hz, transmitting signal with two digital signal levels. what is bit rate for this system? if the digital signal has 4 digital signal levels. bandwidth of noiseless channel is 3000 hz. what is bit rate for this system? telephony channel has bandwidth from low cut off frequency of 300 hz to higher cut off frequency of 3300 hz. signal to noise ratio is 3162 what is the channel capacity (bit rate)? s/n ratio is 36 db and channel bandwidth is 2 mhz. what is the channel capacity for this system?
