Determine the current i 1 in the network. For the code X 1 = (000, 111) how many errors can be successfully detected? The device that exhibits negative resistance region is ___________. The input to a channel is a bandpass signal. It is obtained by linearly modulating a sinusoidal carrier with a single-tone signal. The output of the channel due to this input is given by $$y\left( t \right) = \left( {{1 \over {100}}} \right)\cos \left( {100t - {{10}^{ - 6}}} \right)\cos \left( {{{10}^6}t - 1.56} \right)$$ The group delay (t g ) and the phase delay (t p ) in seconds, of the channel are In resistance level, the AC or the dynamic resistance of a p-n junction diode is defined by
