Okay what came before that:adjustable oscillation frequency in the range 2.4-48khz, output load 24kohm, control of the oscillation amplitude in the range 2.4-12V, the possibility of adjusting the up/down ramps of the triangular signal,operating temperature range 0-70
1. Find a schematic on the internet for a circuit…
2. Ask an internet forum to design a circuit that…
or
3. Design a circuit that…
If it is 3, you have obviously flunked the assignment.
