A 100-W power transistor is operating at a temperature of 60°C. What is the actual power capacity? (Assume a derate 0.57 W/°C above 25°C.)
Sandy has a choice between purchasing % 5,000 in Government of Canada bonds paying 8.5 percent interest or purchasing % 5,000 in BB-rated corporate bonds with a coupon rate of 11.3 percent.What is the risk premium on the BB-rated corporate bonds? ___..
Derive an expression for the optimum value of the avalanche gain opt M for which the signalto-noise ratio (SNR) becomes optimum by using the following expression for the excess noise factor: Fa( M)=KM+ (1-K ) (2-1/M). Assume that M^3 >> M .
Determine the ROM size and contents to implement a function which converts a sign and magnitude number from -5 to +6 to two's complement format.
Assuming the op amp is not saturated, find the Thevenin resistance between terminals (a,b). Since there is no independent voltage or current supply, the Thevenin voltage is zero, and one must attach a test source at (a,b)
How are the left (L) and right (R) signals obtained separately in the radio receiver to drive the dual channel audio amplifier and speakers?
Steam enters a reversible, adiabatic (isentropic) turbine at 8 MPa and 550 oC with a mass flow rate of 3.6 kg/sec. The pressure of the steam flow at the turbine exit is 250 kPa. Neglect the changes in potential and kinetic energies of the flow thr..
A temperature transducer has the relationship R=200 + 10T where R is in ohms and T is in Celsius. The problem specifications are: Range is 30=T=50°C Resolution is 0.01°C Frequencies of interest are 0 to 100Hz Transducer dissipation constant is 20 mW..
The densities of diamond and germanium are 3.52g/cm3 and 5.32g/cm3 respectively. Estimate the number of atoms per unit volume, nearest neighbor distance, and lattice constant for diamond and Ge.
An FM transmitter delivers to a 75 ohm antenna a signal voltage of V (t)= 1000 sin (10^9t+4 sin 10^4t), determine: (a) carrier frequency; (b) intelligence frequency; (c)modulation index; and (d)total power in FM signal
what is the annual value to the plant owner of a 1% increase in the capacity factor of a 1,200-MWe nuclear power plant, in $/year. For example, assume the plant capacity factor increased from 0.875 to 0.885. Disregard the minor effect of capacity ..
Will this system meet the requirements?
