This electronics video tutorial provides a basic introduction into the common emitter amplifier which uses a NPN bipolar junction transistor. This video explains how to calculate the voltage gain, current gain, and power gain of the CE amplifier circuit. Got Questions ! Your Answers> What is the ...
The overall reason for cascading amplifiers is the need for an increase in amplifier output to meet a specific requirement, e.g., to increase the signal strength in a Television or radio receiver. Using a cascade, or multistage, amplifier can provide your design with a high...
To indicate how long theamplifier gaincan remain constant in frequency, we need to define a range of frequencies. Along with that range, the gain should not deviate more than 70.7% of the maximum gain that has been defined as a reference at mid-frequency. In the below-shown curve, f1 an...
There's probably a formula used to calculate the total likely load. Remember not all of your appliances are going to be switched on at the same time (e.g. 4 rings of a cooker plus oven probably wouldn't be on at the same time) so there would be weighting factors for each appliance...
to the inputs to force the output to 0 V. The tolerance error of the resistors is the gain error caused by the corresponding tolerances used for setting the closed-loop gain. Other errors are caused by the bias current, the power supply rejection ratio (PSRR), the open-loop gain,...
Powered mixers offer most of the bells and whistles you’ll find on unpowered mixers in terms of routing options, effects processing, EQing, and much more. As with any mixer purchase, you’ll need to calculate the total inputs and outputs you need as well as the necessary power to drive...
However, if you wish to get the best performance out of your subwoofers, it’s important to set the LPF on your amplifier correctly. If you don’t know how to install an LPF on your amp properly, don’t worry because, in this article, we will guide you exactly on how to do that...
Vertical stacking is used primarily to increase overall gain without appreciably altering the azimuth beam
But the truth is that money makes you more of who you are; money is neutral, an amplifier. So when you start experiencing financial problems… Money sometimes isn’t the problem itself, but your money habits. It’s the same with having a trading journal… ...
The PGA of the PCM2912A actually is controlled by software on the host system, there is no way to change the PGA gain manually on the codec. The PGA level can be adjusted by the native input volume control function of the OS.
