(Dont copy paste the answer pls) 5 different frequencies will be generated using only 1 timer and will be output from different pins of a parallel port. (Frequencies to be produced: , 240, 280, 320, 360, 400 Hz). Frequencies will be generated using a timer; . Mode 1 or mode 2 will be used for the timers.

a) Circuits other than uC require the cosine wave in analog form. In this context, calculate and find the circuit elements to be connected to the ports so as to use the minimum circuit element and draw the circuit elements connected to the parallel port of the uC together with the port.

b) Draw the flow diagram of the algorithm.

c) Write down the algorithm in 8051 machine code.
