hello guys
iam eletronic student ....currently i doing one project with audio amplifier and LED.
i need to design a 0.5w audio amplifier with mute and volume control....the design should allow user to select two different bandwidth....selected choice must be indicated visually using LED...the power supply is +- 12V ...the leval of baseband signal is 250mv pk to pk at 1khz...
components should be used ...MicroA741. TDA7052A, regulator (LM78, L05), transistor 2N2222......
plese guide me on how to design the circuit board....
i need u r help very urgently...thanks in advance...
