derive the BER (Bit Error Rate) of a 8-PAM (Pulse Amplitude Modulation) system in an AWGN (Additive White Gaussian Noise) channel.
Write a function that asks a user it´s name, age and if the user has a spouse. If the user has a spouse, let the function then ask the spouses age. Then let it write out if the user is older,
Design an inverting amplifier using one opamp and two or more resistors. Design it such that it has a gain of -10 (this gain is termed "inverting").Include a schematic of this circuit with the compo
An ECG has a scalar magnitude of 1 mV on lead II and a scalar magnitude of 0.5 mV on lead III. Calculate the scalar magnitude on lead I.
Why are overmodulated and carrier suppressed AM signals a problem from the standpoint of the receiver. Why (in what siuations) might DSB-SC be prefered over standard AM.
