If V_{GS (on)} = 6V I_D(on) = 4mA and V_GS(Th) = 3V so the value of V_DO and, R_D for the given circuit is

A manufacturer of metal pistons finds that on an average 12% of his pistons are rejected because they are either oversize or under-size. [Multiple Select Question]

The sequential circuit shown below is a MOD –_____ counter.

For a lossy dielectric material having μ_r=1, ε_r=48,, calculate propagation constant for at a frequency of 16GHz.

Consider a digital signal detector having a input voltage R = ±2V +n, here ‘2V’ & ‘–2V’ are amplitudes of the received signal & they occur with equal probability & the noise ‘n’ is characterised by a random variable taking the form of uniform pdf as shown in fig below.

Determine the probability of error ‘Pe’ at output of the detectors
