Piletid vastustega

It has also a transformer;Multivibrator:is a rectangle pulse generator with the positive feedback. 7)Advantages:simple principle of operation, low price, high reliability.Disadvantages:unstable and temperature dependent.Output waveform has distortions and changes with time. 8)Monostables:It generates the only pulse after switching on, and on continue operation, an input signal must enter the circuit.The pulse width of the single-short output signal is determined by R and C values.At the initial state, the transistor T 2 passes the current and T1 is closed.The capacitor is charged.After Uin enters T1,the T1switches on and the capacitor closes T2.The capacitor discharges...

Microcontroller homework 4

3. A) Because the mixer needs additional components B) The mixer approach multiplies the frequency shift you want to measure, but also any other frequency shift. This includes drift caused by component heating, noise, etc. 4. The output waveform according to input: 5. A) 100 Hz B) 500 Hz C) 1 kHz 6. In an electrical system, a ground loop usually refers to a current, almost always unwanted, in a conductor connecting two points that are supposed to be at the same potential, often ground, but are...

Book Analog Interfacing to Embedded Microprocessors

If the system measuring this system assumed it was measuring a sinusoid of some frequency, it would conclude that it was measuring a sinusoid exactly half the frequency of the real input. This is called aliasing. Aliasing can occur any time that the input frequency is a multiple of the sample frequency. Also shown in Figure 1.3 is another input waveform that is not a sinusoid. In this case, the system doesn’t assume it is sampling a sine, so it just stores System Design 11 Figure 1.3 Aliasing. the samples as they are read. As you can see, the resulting pattern of data values does not match the input at all. Any system must be designed so that it can keep up with whatever it is mea- suring. This includes the speed...

). This includes noises and heating. - If the input frequency comes down and the difference frequency will increases up and may be filtered aways by the low pass filter. - The design of the mixer is complecated. - The circuit may produce more ElectroMagnetic Interference (EMI) Question 4 (10 marks) Consider the following circuit and input waveform . Draw an equivalent output waveform. Solution: Question 5 (20 marks) Consider the following LM231 voltage to frequency converter (see LM331.pdf). Assume Rs = 17 kΩ. Determine the output frequency (fOUT). a) Vin = 0.0836 V b) Vin = 0.418 V c) Vin = 0.836 V Solution: Determine the output frequency (fOUT). From the chart, Rs = 17 kΩ, RL = 100 kΩ, Rt = 6.8 kΩ, Ct = 0.01 µF. a) For Vin = 0.0836 V, fOUT= 100 Hz b) For Vin = 0.418...

a) Why do we require a low-pass filter when using this mixer circuit? Mixer needs more parts b) Name another disadvantage of such a mixer circuit. The mixer approach multiplies the frequency shift you want to measure, but also any other frequency shift. This includes drift caused by component heating, noise, etc. Question 4 Consider the following circuit and input waveform . Question 3 Draw an equivalent output waveform. Question 3 Question 5 Consider the following LM231 voltage to frequency converter (see LM331.pdf). Assume Rs = 17 kΩ. (Hint: Find the formula to calculate the output frequency fOUT and the values of Rs, RL, Rt, and Ct in LM331.pdf). Determine the output frequency (fOUT). a) Vin = 0.0836 V V¿ 0.0836 ∗RS ∗17 k 2,09 V...
