in a binary DPSK receiver, determine the approximate received power level (in fW) required for a probability of error of 10-6 based on a data rate of 1 Mbit/s, an antenna temperature of 100 K, and a receiver temperature referred to the input of 150 K.
Assume X is normally distributed with a mean of 5 and a standard deviation of 4. Determine the value for x that solves each of the following: (a) P(X > x) = 0.5 (b) P(X
A standard 12-V car battery has an ampere-hour rating of of 30 Ah, whereas a heavy-duty battery has a rating of 51 Ah. the ratio of available energy is 1.7 ratio. Find the percentage increase in available current for starting
What degree of matching in emitter area is required for the base-emitter voltages of two bipolar devices with identical collector currents to have a difference of less than 5.0mV Use VT= 25.85mV.
The Per-cent impedance of a single-phase electric load is 2.5. The base power is 100KVA, and the base voltage is 12.47KV. a find the per-unit impedance of the load if 400KVA and 20 KV are selected as base values.
In a matched CMOS inverter in which Vtn = - Vtp = 0.5 V, VDD = 1.8 V, kn = kp = 600 uA/V^2 and fabricated in a 0.13 um technology, use the average current method to determine W/L ratios such that the propagation delay tp is smaller
draw a state diagram for an FSM with an input gcnt and three outputs x,y, and z. The xyz outputs generate a sequence called a Gray code in which exactly one of the three outputs changes from 0 to 1 or from 1 to 0.
y''(t) = %u2013 25 y, subject to the two initial conditions y(0) = 0.2 and dy(0)/dt = 0. You will need to use integrating op amps for this design. b)What function will the output voltage y(t) be
The battery is made by connecting 5 unit cells in series and then by connecting 7 of these series cells in parallel. Each unit cell has the voltage of 1.25 V and the internal resistance if 3.4 Ohm.
