Consider the microwave network shown below, consisting of a 50 source, a 50 Ω 3 dB matched attenuator, and a 50 Ω load.
(a) Compute the power gain, the available power gain, and the transducer power gain.
(b) How do these gains change if the load is changed to 25 ?
(c) How do these gains change if the source impedance is changed to 25 Ω
Plot the squared residuals on Y axis of model 1 vs. Size and Beds on X axis (separate plots) and comment on the assumption of homoscedasticity in the variance of the error term.
A common-source amplifier utilizes a MOSFET for which VA=12.5 V and is operated at VOV = 0.25V. What is the value of its (gm ro). The amplifier feeds a load resistance RL = 15K ohm. The designer selects RD=2 RL.
Given the following array declaration, if the array is stored starting at address 1000, what is the output of the following statement? Assume the code is for a 32 bit processor such as a Pentium.
F(a,b,c,d) = Σ m(7, 11, 12, 14) + Σ d(0, 10) (a) Find all of the prime implicants of F'. (b) Find a minimum product-of-sums for F. Note: F' is specified in (a) and F in (b).
The electric field outside a uniformly charged, infinite cylindrical conductor is the same as if the cylinder's charge were concentrated in a thin wire along the cylinders axis. Moreover, the potential inside a uniformly charged infinite cylindric..
if the analog signal to be quatized is a sinusoidal wave form x(t)=9.5sin(2000*pi*t), and if the bipolar quatizere uses 6 bits - what are the number of quantization levels - quantization step size or resolution, delta, assuming the signal range
