The needed antenna length (in meters) for a communications system uses a carrier frequency of 145 MHz is: Note: The speed of light approximately 300 million meters per second.  Each side should measure (λ/4)

It is located at one point in space and its purpose is to transform the message signal produced by the source of information into a form suitable for transmission over the channel?

Describe the difference between nonselective and selective debridement and provide a debridement method for each.

Frequency response based design: Lag Consider a unity feedback system with the plant Gp = 1 / ( (s+3) (s2 + 2s + 4) )  Here is some information from the Bode of Gp(s): At frequency ω = 0 rad/s magnitude is -21.6 dB  and phase is 0  degAt frequency ω = 2.24 rad/s magnitude is -24.7 dB   and phase is -140  degAt frequency ω = 7.85 rad/s magnitude is -54 dB   and phase is -234  degAt frequency ω = 69 rad/s magnitude is -110 dB   and phase is -266  deg Compute the gain K that will yield overshoot Mp=0.254. Using the gain K from part (a), compute the parameter α of a lag compensator so that the steady-state error to a unit step reference input is  0.02. Determine τI such that the desired phase margin does not change too much. Does the choice of τI affect the steady-state error?   Do the work on paper showing all the steps (which you’ll submit later) but type below your K,  α  and τI
