Suppose a transmission channel operates at 10 Mbps and has a bit error rate of 10-2. Bit errors occur at random and independent of each other. Suppose that the following code is used. To transmit a 1, the codeword 111 is sent; to transmit a 0, the codeword 000 is sent. The receiver takes the three received bits and decides which bit was sent by taking the majority vote of the three bits. Find the probability that the receiver makes a decoding error.
Define Root Locus and Routh-Hurwitrz, Use Routh-Hurwitz to find vales of K so that L = k (s+1) / (s^2 +4) (s+10) has poles to the left of s= -2
Calculate the %age second harmonic distortion present in the amplifier's output for a sinusoidal input of 10 mV r.m.s.
a 10 ohm resistor is connected across a 12 v battery. How much current is there through the resistor?
Solve the equation z^2+z+1=0 using z=(x,y) and the basic definitions. (Hint: Note that y does not equal 0 because the equation X^2+X+1 does not equal 0 for any real number x.)
The probability that a person will install a black telephone in a residence is estimated to be 0.3. Find the probability that the tenth phone installed in a new subdivision is the fifth black phone.
