Develop a functional design for a system that measures and displays the speed of a bicycle. Be sure to clearly identify the design levels, function requirements, and theory of operation for each level.The system must:• Measure instantaneous velocities between zero and 75 miles per hour with an accuracy of 1 % of full scale.• Display the velocity digitally and include one digit beyond the decimal point.• Operate with bicycle tires that have 19-, 24-, 26-, and 27-inch diameters.
1. Consider the Nordex 1.3MW, 60-m wind turbine with power specifications given in table 6.7 located in an area with 8m/s wind speeds. a) find the average speed in the wind (W/m^2) assuming Rayleigh statistics.
A bandpass filter with a center frequency of 6kHz, a 3dB banwidth of 1 kHz, and a 50 dB bandwidth of 2kHz is connected to a signal generator that outputs a one volt square wave at a frequency of 2kHz. A spectrum analyzer is connected to the filter..
a defibrillator supplies a maximum energy dosage of 20 jouls, and the maximum voltage of 8 volt. suppose it is desired to charge the capacitor from an ideal DC current source, and they want to do it in less than 80 seconds.
(a) Design a simple PNP current source to give an output current of IO = 0.5 mA (nominal value). The transistor parameters are f = 50, VEE = 10 V, VCC = 10V, |VBE| = 0.7 V, |VCEsat| = 0.3 V and VA = 50 V (for all transistors)
Design an analog divider circuit with a minimum number of op amps with Vo = f(V1/V2) where V1 and V2 are inputs of the circuit and Vo is the output and derive Vo in terms of V1 and V2 and the circuit elements.
Design 3 stage amplifier with the following requirement input signal = 5 mV with R=10k ohms over all gain > 1000 power supply: Vcc = 5V, Vee = -5V Rin > 1 Mega Ohms Rout = 100 ohms 1st Stage BJT must use inverting
Suppose that you wish to offer a voice over IP wireless service. The target packet error rate (or drop rate) is 10^3 and you determine that if the signal is confined to within a coherence band, about 20% of the packets are dropped due to fading.
Earth-based 802.11a or 802.11g wireless LAN standards transmit data using a bandwidth of 16.56 MHz. What is the theoretical thermal noise level (in V) in an ideal receiver operating with an input impedance of 50 ohms
Design and implement a sequence detector using a finite state machine that detects the sequence 1, 1, 0, 1, 0. Consider previous/oldest bits for the sequence detection. Design the fuction using D-Flip-Flop
A bar of p-type silicon, has a cross-sectional area A = 10-6 cm2 and a length L = 1.2 x 10-3 cm. For an applied voltage of 5V, a current of 2mA is required. What is the required (a) resistance, (b) resistivity, and (c) impurity doping concentratio..
If the application program creates a message of 150 bytes and each layer (including the fifth and the first) adds a header of 20 bytes to the data unit, what is the efficiency (the ratio of application layer bytes to the number of bytes transmitte..
When a type of integrated circuit is tested at 185 degrees Celcius, 10% of the circuits fail within two weeks with VDD = 1.0V. Estimate the 10% lifetime at 95 degrees Celcius and 1.0V assuming Ea = 1.0eV.
