A digital filter is to be designed using bilinear transform method. The expected frequency response specification of the filter is given in the following figure. fS = 8,000 Hz.
I. Specify the filter frequency response versus normalized frequency,ohm=2pi f/fs
II. Compute the critical frequencies to obtain the corresponding analog filter specification when the critical frequencies are pre-warpped to meet the digital filter requirements.
The transmitter has a power of 7 watts and the receiver needs at least 266 milliwatts to operate. Which is the maximum attenuation in dB allowed (value must be negative)
noncausal, linear, and time-invariant. Determine the impulse response for the system and verify that an LTI system defined by the impulse response you determined satisfies the difference equation.
Sam (75 ) takes off up a 50--high, 10 frictionless slope on his jet-powered skis. The skis have a thrust of 200 . He keeps his skis tilted at 10 after becoming airborne. How far does Sam land from the base of the cliff
For PID control, what are roles of integral term and derivative term. Given KP=10, KI=3, and KD=4, write down this PID controller function.
Titan has numerous hydrocarbon lakes containing a mix of methane and ethane in unknown proportions. A small submersible vehicle will exlpore Kraken Mare, the largest lake.
A 480-V, 60Hz, 500-hp 0.85-PF-leading eight-pole delta-connected synchronous motor has a synchronous reactance of 0.6 ohms and neglible armature resistance. Ignore its friction, windage and core losses for the purposes of this problem.

MOS (p and n) npn and pnp transistors with parameters given in the text or select your own by using industrial data sheets, available on the internet. Also resistors, capacitors, and power supplies (10 V, 5 V, and 3.3 V) are available.
When we discussed the work of Galvani and Volta, we noted that Galvani's work was not fully appreciated until the development of instruments capable of detecting and amplifying the small biopotentials present in living organisms.
Design an integrator whose output voltage Vo(t) is related to the input voltage Vin(t) by Determine the rate of integrator drift with Vin = 0 if the input-offset voltage VOS is 2mV
An SSB generator has a 9 MHz carrier and is used to pass voice frequencies in the 300- to 3300-Hz range. The lower sideband is selected. What is the approximate center frequency of the filter needed to pass the lower sideband.
