Several types of special-purpose diodes exist.One is the constant-current diode for which the current is constantover a wide range of voltage. Another special type is thelight-emitting diode (LED). Sometimes, the series combination ofthese two devices is used to provide constant current to the LEDfrom a variable voltage. Sketch the overall volt amperecharacteristic to scale for the parallel combination of these two.
a.) Find transfer function H(w) of a matched filter for thispulse. No time shifting is necessary. b.) Find the impulse response h(t) of the matched filter. c.) Find output waveform y0(t) of the matched filter.
A 600 V, dc shunt motor has armature and field resistance of 15 ohms and 600 ohms respectively. When the motor runs unloaded, the ine current is 3 A, and the speed is 1000rpm. Calculate the developed torque at a full load armature current of 50 A.
8 bit DAC with a 5 volt reference connects to a light source with an intensity given by Il=45V^(3/2)W/m^2 a. what is the range of intensity that can be produced b. what intensities are produced by digital inputs of 1bh, 7ah,9fh,e5h
An angle modulated signal is given by EM(t)=5cos[Wct + 20sin100pi(t) + 10sin2000pi(t)] a. Find the power in the modulated signal b. Find the peak frequency deviation in Hz. c. Find the peak phase deviation in radians. d. Find the bandwidth
Plot how this absorbed power varies with signal strength W12, and discuss the behavior especially at very small and very large W12. Where does the absorbed power go? -and how does it get there?
A transmitter transmits an AM sinal with a carrier frequncy of 1530kHz. When an inexpensive radio receiver (which has a poor selectivity in its RF-stage bandpass filter) is tuned to 1530kHz, the signal is heard loud and clear.
Design an assembly code to open a vault (after entering the correct 4-number sequence "1234"), it displays it in the 7 segment display, than it displays the word OPEN when the correct sequence is entered.
Design, a simple RLCcircuit which can be used to display both an underdamped andoverdamped natural response. The circuit design and componentvalues are up to you. The key is to keep it simple - asimple circuit, and a simple adjustment
Design a circuit using JK flip-flops that takes in a binary stream B0B1B2B3 and outputs 1 at a time t if the stream recieved thusfar (i.e. BoB1..Bt-1Bt), when read as an unsigned binary number, is divisible by 3.
A lot of size N= 30 contains three nonconforming units. What is the probability that a sample of five units selected at random contains exactly one nonconforming unit what is the probability that it contains one or more non conformances
a) Calculates the average of the contents of the data array b) Calculates the product of the contents of the data array c) Calculates the product of the elements of the even rows of the data array d) Calculates the product of the elements of the even..
An engineer intends to study an input signal with frequency components of 5, 6, and 10 kHz. It is desired that all other frequencies be filtered out. A) What kind of filter does this require
