So the function generator designers have embedded a 50 ohm load as the output impedance of the scope and purposely deliver twice the desired amplitude.
When connected to a 50 ohm load, the resulting voltage divider provides the right amplitude because it has a gain of 0. In our class, load impedances e. You will need to readjust it. Scope loading high frequency signals? That is, are the high frequency signals being attenuated?
Seeing ringing on probe? The probe may need to be compensated. Please do not attempt this task yourself on the lab probes.
Simple Electronics Projects for Beginners
However, recognize how it is done and file it away in your long-term memory for the next time you see ringing on a scope. Scope keeps "auto-probing" to some strange setting? Most of our probes have a small spring-loaded sense pin at their oscilloscope connection. Placing a small piece of paper between this pin and the scope should prevent the scope from trying to automatically change the probe settings.
Cleaning these contacts may improve the situation. Digital multimeter DMM will not turn on. While the DMM dial is turned to something other than "Off," press the two buttons under the display simultaneously.

The DMM should "wake up" and be operable again. If the DMM is left on for a few subsequent long periods of time without much use, it will enter this sleep mode.
Power supply noise e. Use a bypass capacitor across your power rails and possibly near your circuit elements.
Choosing the size and type of each of these can be complicated. A good rule of thumb is to put pretty large capacitors e. Circuit acting like your capacitor has too much capacitance?
Stray parasitic capacitance is everywhere. In fact, the pins of an IC and the air between them form a capacitor of at least a few picoFarad. If you can, try to choose circuit elements that dominate over or compensate for these strays.
If setting an RC, choose a low R to give you a high C; however, realize that the low R may result in a higher power draw from your circuit.
Oscilloscope saved TRC files and now you have no way to open them. If you have a bunch of TRC files, setup a time with your instructor to visit the lab. However, you may lose some data in the conversion process.
When choosing resistor and capacitor values for your oscillator e. Assume that the breadboard and chip pins contribute a few Ohms even as many as ten or twenty of resistance and a few picoFarads of capacitance to your circuit.
Because of this, keep your resistances greater than a kiloOhm and your capacitances greater than 10 nanoFarad. Resistances lower than this are bad for your circuit anyway because they probably mean your burning too much power off.

Though simple in nature this circuit will help you to understand how real-world electronics systems are built. This circuit is a basic one which senses smoke to detect fire and hence produce an alarm to warn people around.
Lead-acid battery charger Objective:- To charge a battery. So why not try your hands at charging a lead acid battery? Here is a simple electronics project that will let you charge your battery.
This circuit is very simple in nature which consists of an LM IC which provides correct charging voltage , a couple of resistors, capacitors and a potentiometer.

How can we avoid audio electronics projects? As written in the objective, our aim is to design and implement a simple audio amplifier using IC TL as a preamplifier. A much advanced audio amplifier project is given below. We recommend you to g through all comments section to understand various problems faced by our readers while implementing this circuit.Though simple in nature this circuit will help you to understand how real-world electronics systems are built.

This water level indicator circuit is easy to implement and is composed of least components. Now, the small offset potential at the OA input will show itself as an amplified, yet hopefully still small, offset in the output. While the DMM dial is turned to something other than "Off," press the two buttons under the display simultaneously.
Therefore, nulling offset is a much more complicated problem in a product that has a lifetime longer than one class time. We recommend you to g through all comments section to understand various problems faced by our readers while implementing this circuit.
