a power source outputs 30 watts of power that is equally divided into four branches. the first and second branches feed access-points that lose a quarter of the power each by the time the power gets to them, while the third and fourth branches lose 3 dB of power each before the power gets to the access points. find the average of the powers in dBm that all four access points receive.

Find an expression for the current gain (iL/iS)

Which of the following provides the process transconductance parameter? a. W/Lµ„Cox b. none of the options c. H„Cox d. LIW u„Cox Clear my choice

Q4:Channel 1 of two channels PAM system handles 8KHZ signal : Channel 2 handles JOKIZsignals. The two channels are sampled at equal intervals of time using very nurrow puises at the lowest frequency that is theoretical adequate The sampled signals are time multipiexed and passed through a LPF hefore transmission. What is the minimum clock frequency of the PAM system? What is the minimum cut off frequeney of 1 PF used before transmission that will preserve the amplitude information on the output pulses. What would be the minimum bandwidth if these channels were frequency, multiplexed.using AM technique and SSB technique? i) ii)
