A method of multiple accessing where a given RF channel bandwidth is divided inot smaller frequency band. AsiaSat I covers how many countries in Asia? The largest error between reference input and output during the transient period is called: On which of the following factors does the value of critical current density in a superconductor depend? If the functions W, X, Y and Z are as follows $$\eqalign{ & {\text{W}} = {\text{R}} + \overline {\text{P}} {\text{Q}} + \overline {\text{R}} {\text{S}} \cr & {\text{X}} = {\text{PQ}}\overline {\text{R}} \overline {\text{S}} + \overline {\text{P}} \overline {\text{Q}} \overline {\text{R}} \overline {\text{S}} + {\text{P}}\overline {\text{Q}} \overline {\text{R}} \overline {\text{S}} \cr & {\text{Y}} = {\text{RS}} + \overline {{\text{PR}} + {\text{P}}\overline {\text{Q}} + \overline {\text{P}} \overline {\text{Q}} } \cr & {\text{Z}} = {\text{R}} + {\text{S}} + \overline {{\text{PQ}} + \overline {\text{P}} \overline {\text{Q}} \overline {\text{R}} + {\text{P}}\overline {\text{Q}} \overline {\text{S}} } \cr} $$ Then (a) W Z,X Z = = (b) W Z,X Y = = (c) W = Z, X = Y (d) W Y Z
