capacitors for power spikes
This is Correct!
As is well demonstrated electrolytic capacitors have bad frequency response. One may model them roughly by a capacitor and an inductor in series. What I here intend to add is to keep in mind to place a 100nF capacitor near every block of circuit...
I have connected a matrix of 6×4 switches to a mega 32 so that I can give it commands. In order to do that, I have ORed the row switches and connected the result to the interrupt pin. So when a switch is pushed the interrupt service routine is executed. The idea works except for the time I...
how to use 2n3904 in multisim
Design starts with the statement of the specification: for example u may wish to design a single stage transistor having gain 100 output resistance 1kΩ and input resistance 100kΩ. Then, assuming u choose to use a silicon BJT transistor, U could proceed to pick...
Re: PLL Question
The fact that the loopgain depends on several parameters including VCO gain and PD gain is for sure. but the main parameter in the hands of the designer is the filter. What Im proposing is that the break frequency of the filter could change in different situations.
Re: FET transistor
For obtaining minimum noise figure U should first obtain the noise parameters of the transistor though experiment, simulation, or datasheets. Then, using these parameters u can draw constant noise figure circles on the smith chart. considering other options like gain...
Re: Receiver Schematic
Please give Ur request in some more detail, like the receiver is analogue or digital. In either form the receiver could take several forms such as AM FM SSB VSB for analogue and FSK, PSK and so on for digital. also the receiver could be superhetrodyne
In digital embedded electronics u could try something with microprocessors like AVR. For example u might want to control an appliance from the internet using AVR. In antenna subject U might find it interesting to design microstrip antennas which is an up to date subject.
I intend to find the peaks ant troughs of the output of a gilbert multiplier in a pll though a differentiator and then sample these points. The difference between minima and maxima is simply the DC voltage. Is that feasible?
