Let U and V be two independent zero mean Gaussian random variables of variances 1/4 and 1/9 respectively. The probability P(3V ≥ 2U) is
A device has 200 Ω equivalent noise resistance, 300 Ω input resistor, and the bandwidth of the amplifier is 6 MHz. If the operating temperature of the amplifier is 290° K, the noise voltage at the input of a television RF amplifier will be nearly

Air craft of Jet Airways at Ahmedabad airport arrive according to a Poisson process at a rate of 12 per hour. All aircraft are handled by one air traffic controller. If the controller takes a 2 – minute coffee break, what is the probability that he will miss one or more arriving aircraft?
A random process is defined by X(t) + A where A is continuous random variable uniformly distributed on (0,1). The auto correlation function and mean of the process is
The auto correlation function of a stationary ergodic random process is shown below.
