Determine the notation that specifies the condition of periodicity for a continuous time signal ?Group of answer choicesx(t) = x( t +T0)Nonex(t) = e^-αtx(n) = x( n+ N)

Q.(1) Determine whether the following DT signals are periodic or not. If periodic, find the period.(a) x[n]= cos(0.3 πn) u[n] (b) x [n]= cos(0.3 πn+0.5 π) u[n](c) x[n]= cos(0.3 πn)+ cos(0.5 πn) (d) x [n]= cos(0.3 n) u[n

he signal x(t) = e^(-5t) sin(t) is1 pointPeriodic and aperiodic bothNothing can be said.periodicaperiodic

Choose an appropriate option that correctly defines periodic signals.Group of answer choicesNoneThe signal that changes with timeThe signal that repeats itself in timeThe signal that changes with frequency

A discrete time periodic signal is defined as x(n)= x(n+N), what is the significance of N?Group of answer choicesSamples/ twice cycleNoneSamples/CycleRate of change of the period

if any discrete time signal is multipled by unit step then is it periodic
