audio amplifier circuit+proteus question

hello everybody,

i am new to proteus, and i am working on audio amplifier circuit, that circuit in the attachment, and i need to simulate the output signal before the speaker, to test the amplification of the input signal

i could simulate the input as shown in the picture, but i don't know from where i get the output label to put on schematic and then simulate on the graph

i got the output from terminal mode, but its without label to add to the graph, so anyone can help with this?

On the main toolbar under "Graph" click on "Add Traces" to add probe names.

Why don't you just use the virtual oscilloscope to check input and output signals? Look on the LHS toolbar under the meter icon to add virtual instruments.

Since your schematic is covered with a grid and has a grey background then it is hard to see. Also its parts and text are small because they are far apart.

Your value for C3 is so low that it cuts frequencies at 1067Hz and lower. Audio goes down to 20Hz.

okay, thanks for your replies,

it worked for me, and i just had to add the voltage probe at the output place , then add traces , then simulate

Thanks again
