Part (A)

How we generate random bits by using 8051 assembly language programming.
but how ??
*( do you have any assembly language program OR any useful thing regarding it i m very thankful to you)

Part (B)

how we generate following triangular by using Assembly language
8051 programming.???
*( do you have any assembly language program OR any useful thing regarding it i m very thankful to you)

part (c)

finally how we connect random bits with triangular wave when random bit is 1 then
"triangular wave 1" will transmit and when random bit 0(zero) then
"triangular wave 2" will transmit. these all process should be done by 8051
assembly language programming but how ??
*( do you have any assembly language program OR any useful thing regarding it i m very thankful to you)

part (d)

It is most important part. after selecting triangular wave 1 or 2. How we transmit these triangular wave by using "pulse amplitude modulation(PAM)" or you can say that modulate by "pulse amplitude modulation" and then transmit.
Pulse represent by one of M = 2^k pulse amplitude values. Thus with k= 2 pulse amplitude values. The PAM signal when the bit rate Rb is fixed the symbol interval is

T = k / Rb = kTb

*( do you have any assembly language program OR any useful thing regarding it i m very thankful to you)

Note: i m really appreciate if u give detail answer with example
