Parts of the circuits, from which, perhaps, a simple radar will be made.
9z. Schematics.
9z.0 Short pulse gen.
Testing triggers to find out how short a pulse I can get - shortpulse.
Testing two simple TTL-based generators to find out how stable they are - shortpulse-two. Different triggers and approximate pulse lengths that can be easily obtained - shortpulse2.
9z.1 Generation of a random sequence of pulses and Gaussian noise.
Pseudo random sequence on 8-bit shift register and 'exclusive NOR' - random8bit.
