1. A tuned circuit has a Q of 60 at 5 MHz. Find its bandwidth at 5 MHz and 20 MHz.
2. A receiver has a sensitivity of 0.3 µV. The same receiver can handle a signal level of 75 mV without overloading. The receiver has a blocking dynamic range of 80 dB. If the desired signal has a level of 10 µV, what is the maximum signal level that can be tolerated within the receiver passband?
3. An FM detector has a sensitivity of 50 mV/kHz. What is its maximum rms output voltage from a broadcast FM signal with a maximum deviation of 75 kHz?
4. How much stronger, in decibels, is an S-9 signal compared with an S-1 signal?
A 500-kVA, 60Hz, 5000V, Y-connected, 10 pole synchronous has internal parameters of Armature Resistance 1ohm amd Synchronous Reactance 10ohms. The generator is operating at rated values and 0.9 pf leading.
select a window function to limit the number of samples of an infinite impulse response and the filter specifications are the same, regardless of which window function you select. If you are given the option of using either a Hamming
Characteristics of a filter, A filter has the following characteristics: Attenuation = 3.0 dB from 0 Hz to 2 kHz. From 2 kHz to 20 kHz attenuation increases from 3 dB to 23 dB in a straight line when plotted on axes of power in decibels (vertical a..
Design a five section high pass lumped element filter with 1 dB equal-ripple response, a cut-off frequency of 1 GHz and an impedance of 50 Ohms. Plot the amplitude and phase response of the filter.
Write a program that asks a user to input (one at a time) the four numbers to fill a 2x2 matrix. For each number entered, make sure the user knows which number is being entered.
An InP TED is 0.5 pm long with a cross sectional area of 10" cm2 and is operated in the transit-time mode.(a) Find the minimum electron density no required for transit-time mode.
Give an example of an RC circuit whose transient behavior cannot be modeled by having a function generator with square wave output replacing the mechanical switch.
Calculate the PMOS device with to acheive symmetric propagation delays in an inverter (tPLH = tPHL). Use Wn=450nm Ln =300nm and Lp=300nm and solve for Wp. So I think by some ratio I can find what Wp should be, maybe something like Wn/Ln=Wn/Lp
A fluid flows through a turbine at the rate of 45 kg/min. Across the turbine the specific enthalpy drop of the fluid is 580 kj/kg and the turbine loses 2100 kj/min in the form of heat energy. Determine the power produced by the turbine.
Evaluate the TL parameters. Include the effect of the earth as ideal. Do not incorporate the effect of the shield wires.
1) Find the transient and steady-state responses of the system using frequency domain methods. 2) Find the forced and natural responses of the system using frequency domain methods. 3)Find the 0+ conditions for the system's step response and impulse ..
A PWM is used in 8-bit mode to produce a signal with a 1 msec period and 60% duty cycle. Determine the value required for any pre-scaling, and the values for the period, and duty cycle registers. The E-clock is 24 MHz.
