電波が見える教科書と、いじれる実験室。 無線通信ブートラボは、無線工学を「読む・触る・確かめる」の3ステップで学ぶアプリです。第一級陸上無線技術士(一陸技)の3科目(無線工学の基礎・工学A・工学B)に準拠した構成で、アマチュア無線や陸上特殊無線技士の学習にも使えます。 ■ 教科書 — 動く図で読む ・図はすべて本物の計算。変調度のスライダーを動かすと、側波帯がその場で伸び縮みします ・FMのスペクトルはベッセル関数を実際に数値計算して描画。搬送波が消える瞬間が見えます ・数式はタップで「マイ公式帳」に保存。あとからいつでも見返せます ■ 部品図鑑 ・抵抗器からマグネトロンまで、回路部品を図記号と頻出公式で1ページずつ解説 ・部品が主役の教科書の章へもワンタップで飛べます ■ 無線シミュレータ ・送信機→伝搬路→受信機のブロック図。変調方式・周波数・距離をいじると、送信電力・伝搬損失・受信SNRの読み値が連動して変わります ■ 演習 ・全問オリジナル作問。解説からは「答えの数字が読み値として出ている」シミュレータ設定にジャンプできます ・間違えた問題は復習キューに自動で入ります ■ 設計方針 ・アカウント登録は不要。学習データはすべて端末内に保存され、外部に送信されません ・白基調の紙のような読み心地と、夜の実験室のようなブラックモード(外観切替)
