5- A synchronous TDM with four 2 Mbps data stream inputs and one data stream output. The multiplexing unit of data is 1 bit. The input bit duration is us; the output bit duration is ps; the output bit rate is ---- Mbps; and the output frame rate is ..........

The minimum bandwidth necessary to pass this signal without excessive distortion is MHz. (Note: to = T Duty Cycle; T= 1/F) 8. Ten channels, each with a 200 kHz bandwidth, are to be multiplexed together using FDM. The minimum bandwidth of the link is KHz when there is a need for a guard band of 10 kHz between the channels; while the minimum bandwidth of the link is KHz when there is a need for a guard band of 20 kHz between the channels. 9. If a channel can transmit a range of frequencies from 10 MHz up to 23 MHz this means this channel has a bandwidth of -------- MHz. 10- A video signal with light variations that change at a frequency as high as 4 MHz. The minimum sampling frequency for A/D conversion is --- MHz. Also, if we sample the signal at 7 MHz rate, then the alias frequency is MHz
