The following 5 signals are to be sampled at the Nyquist rate and multiplexed and transmitted by the means of TDM.
X1(t) band-limited to 2.5kHz
X2(t) band-limited to 2.5kHz
X3(t) band-limited to 10kHz
X4(t) = sin 5000 ? t
X5(t) band limited to 5kHz

- If we have a resistor physically but its color bands are not visible, then how can we calculate the value of resistor?arrow_forwardThe main equation we are using to measure the e/m ratio is: (e/m)=((2v)/(r2B2)) If the anode voltage V is increased by 4 times and the magnetic field was kept constant, the electron beam's deflection radius will be doubled. If we plot V as the y-axis and r2 as the x-axis the slope is equal to: A) (e/m)B2=slope B)(e/m)=slope C)(e/m) (B2/2)=slopearrow_forward
