with the next "hardware" program in c the next signals

Assume CK=1MHz

1. Make a program that generates the following 3 signals simultaneously:

Signal of square pulses using CTC in PD6 (OC0A) of 1900 Hz.

Square pulse signal using CTC on PB1 (OC1A) of 1700 Hz.

Square pulse signal using CTC on PB3 (OC2A) at 1600 Hz.

2. Make a program that generates the following 3 signals simultaneously,

Signal of square pulses using CTC in PD6 (OC0A) of 368 Hz.

Square pulse signal using CTC on PB1 (OC1A) of 268 Hz.

Square pulse signal using CTC on PB3 (OC2A) of 168 Hz.

Assume CK=8MHz (it is enough to put at the beginning of the program CLKPR=0x80; and CLKPR=0;)

3. Make a program that generates the following 3 signals simultaneously:
